So I saw this adorable puffer fish at WalMart and I want to buy him because I feel that he needs to be rescused from that awful place. I already have a 50 tank but I dont want to add him into that community because I have too many small fish. So, I have a reserve 10 gal tank and I was wondering if I saved only one puffer and did consistant water changes would he be okay in a 10 gal tank?

    A 20 gallon is recommended. I think if you were just going to use the 10 gallong very temporarilky - it would be OK - otherwise it is just too small.

    I have 2 spotted green pufferfish in a 3 gallon aquarium and both are doing good together. I did have them in a 1 1/2 gallon aquarium and they did fine in it. They get along. I clean the tank once a week and add a little aquarium salt in it. I also use an air pump in the tank too. I feed them twice a day. They like the freeze dried shrimp. I have had them for about 5 months and they are growing.

I just bought a spotted puffer and a blood parrot cichlid from wal*mart. Unfortuanently, the blood parrot cichlid is a bit mean and nips at my puffer fish. My puffer fish just stands vertically wedged between the filter and the corner of the tank (he is able to get out) and stays there for hours. They live in a two gallon fish tank with a temperature of 72 degrees, they have plants and rocks and a cave. Is he just getting used to this new enviroment or is this not a good habitat for him?

    Your tank is way too small. You need at least a 10 gallon just for the puffer. At least. Otherwise you are running a big risk of stunting, agression and death. For the two, you need at least a 20 gallon. Might want to read up on whether they can be OK tank mates as well.
  • Fran - 2011-08-29
    Both Cichlids and Puffers are incredibly aggressive. I have both. - Not in the same tank. The previous reply is right you need at least 10-15 gallons for your little puffer but I wouldn't recommend putting him in a tank with anything. The only thing that might survive in a tank with him is an octo or a loach. No promises though. I had an albino catfish in with mine for a year and then one day he just up and ate him for sh*ts and giggles. They can snap at any point and eat your whole tank. You probably know this, but they have teeth and you need to give them crunchy snacks (like little snails) or else their teeth overgrow, they can't eat, die etc... Hopefully you also know that green spot puffers live in brackish water- you can look it up just read a little bit they are pretty low maintenance once you figure out some basic facts about them. Oh, and cichlids are just jerks they nip at everything even their own kind.

Okay, so I have 1 puffer in a 30 gallon tank, and it's been totally fine, but I came home one night and he was sitting at the bottom of the tank, his spots are dissapering and he's all dark with a little black on his belly. He hasn't moved from that spot for 2 days now, and is breathing very deeply. He now has this thick clear coat forming over his eyes. What do I do?? ):

    Aniaml World article on Fish Diseases and recommended Treatment link
    Check out the symptoms and see if something corresponds to what you see. I didn't see anything specific - cloudy eye - sounds like you got a bacterial thing going on though.

    I think (know) you are placing to many fish in a 40 gallon. Rule of thumb is 1 usable gallon (subtract gallons out for decorations and gravel) for each one inch the fish are going to be as adults. Otherwise you will have stunting, possibly death and definite agression. So the Puffers need about a 15 gallong tank on their own for the two. Community fish are supposed to get along and for the most part they do. However, humans are supposed to get along also and there is always a Ted Bundy or Jeffry Daimer in the midst. Your fish need plenty of room and they need their own safe territory and mixing many together - even if community fish - in too small a tank is a recipe for problems.

I have 3 GSP in my 20 gallon tank w/ Lg rosy barbs. 2 of the GSP are doing very well. 1 looks like he is starving, any ideas?

    You need a 20 gallon tank for 1 pufferfish and you have 3. You need at least a 50 gallon tank. That would help. Tank is too small they gang up and try and reduce the population so maybe they are not letting the 3rd puffer eat. What happens when you try and feed them? Do the two prevent the third from eating? Until you get a larger tank can you put a divider in to let the 3rd one eat?
  • Daniel Yap - 2011-07-09
    Separate the hungry little guy to another tank. 2 of your puffer might be bullying it.
    Hey, don say its not true. I have experience about this little guy, so hurry before its too late

I just got 5 puffer fish. I love them. I love watching them swim around. I lost 12 puffers when I moved to my new house because of the water. I hadn't thought about getting any more untill I went to the store and found some bigger puffer fish then what I had`before. I couldn't resist myself. I have a rain bow shark and upside down shark and some guppys in my tank will the sharks mess with my puffers?

    WOW there seems to be greatly varying points of view on this. There is everything to absolutely no other tank mates to any non-agressive community fish that is larger than the puffer is fine. They are agressive and big time fin nippers. Many tank mates just dissapear. They should be able to be with their own kind or definitely recommended that the other fish be nice community fish. Large tank and no crowding with plenty of plants and hidey holes.

    In a community setting, be sure there is plenty of room and that the aquarium is well planted. It can also have a variety of other decor such as rocks and roots. Place the decor in a manner that breaks their line of site and provides plenty of retreats for all the fish.

  • Daniel Yap - 2011-07-09
    Well, maybe only their own kind they will tolerate, They're racist, except if you set up some hiding space for the other fish.

    I have molly fish in with my puffers and they don't bother each other but of course I make sure there is plenty of room and hidding places. I havent lost a fish in months so I would say try some mollies.

    I have two gsp in my tank. They seem to get along fine with my rubber lipped pleco's and albino rainbow sharks.

My puffer fish is just floating there. We have changed the tank several times. It seems like every week it starts to stink! We have the correct temperature and brackish water for the green puffer. We have the bubble maker to help oxygen flow and a filter. He looks really sick, Help!

    Where is the water coming from? Purifying tablets, chlorine? Something is strange if the tank is smelling that bad. I also included link for Fish Disease and Treatment Look up symptoms and also tank conditions. Corresponding treatment is recommended.
  • Betta Care - 2011-07-23
    Check for water source, I suggest you get water from a different source and treat it with conditioners available in pet stores before you let your fish in. Also make sure that the water is run through a new filter before you let your fish in. I suggest you check the following 2 sites which give a lot of information about fish care and

    All the best !

We have a GSP and it looks like his teeth are getting really long, not sure if he is eating. In the one comment someone said you could clip their teeth. Just wondering how you go about doing this?

    Have you tried feeding them snails first and letting them wear down their teeth first? Try that first. Animal World article says "Puffers have strong teeth that grow throughout their lives, so are prone to overgrown teeth. Offer hard shelled live food often to keep the teeth worn down. Feeding snails daily will help to wear down the teeth. If the teeth get too long, they will be unable to eat, requiring the owner to clip the teeth".
  • Teresa - 2011-06-21
    Hi, I just read that the Green Spotted Pufferfish rerquires certain types of hard crustacean food in order to keep their teeth trimmed naturally. I do not know what this food is exactly, but you could find out from a pet store familiar with this type of fish.
    Good luck.
  • Daniel Yap - 2011-07-09
    Well, maybe you should use nail clipper :p
    There's no guarantee they will stay still.
  • Chelsee Coffin - 2011-07-11
    i have several GSP and I go to the pet store and stock up on "pest snails". Most pet stores will give them to you or they might charge you a small fee but there are usually tons of them and I can tell from my GSP's that they love them. I've had mine for almost a year now and I've never had to clip their teeth. If anything go around to all our local pet stores and stock up on pest snails. Put them in there own tank and let them breed. And only put 1-2 of them in with your puffer a day. If you do this you most likely will never have to go to the pet store to get more ever again.

My puffer is sick.....I think! He has gone from a white belly to a gray belly back to white and back to gray. I have tested the the salinity and the ph and I think it was ok. He is not eating and there are ghost shrimp minnows and snails in the tank. His teeth don't look long.....that is if I know what I'm looking at. I think he was cold too so I warmed the water. Please help!!!!!????

    Don't panic - at least not yet. Puffer fish do change colors. They do it in their natural enviornment with some degree of regularity and they also do it in an aquarium situation but less frequently. The color change is many times due to stress - temperature change in water or condition of water or too many fish in the tank etc. Obviously, it can also be because he isn't feeling all that great. I have included an article "Fish Disease and Treatment" from Animal World. Check the tank enviornment throughly. Also, what size is your aquarium? It is recommended for 1 puffer that a 20 gallon be used and if there are other fish to go to at least a 50 gallon. Good news it is not unusual for puffers to change color, but the YUK news is that it is usually do to stress. Check the tank conditions and do the recommended treatments. Not eating is also a sign of stress.
    Read the article on the Puffer because the tank enviornment required is there. Also to be careful of amonia and nitrates as they don't necessarily eat all their food so tank gets messy. Also article says to change 30 - 50% of the water per week. Bunch of little things that can be happening here but let's just check them out one at a time. OK?
  • Daniel Yap - 2011-07-09
    You are crazy, warming up the water sometimes makes matters worst....
    It's normal 4 a green puffer to change colour of the belly. It's a healthy little guy, except if it stays with grey colour.....
