We had two of these in a tank with assorted guppies, and they killed one of the guppies and were nipping at the others before I removed them. What could cause this?

    Tetras can be a bit nippy at times.  May need to add more tetras so they will school and this will normally keep that behavior in the group.

    Most common reason for a group of fish to stop eating is water conditions.  Test your water levels with some test strips or bring a water sample into the pet store and ask them to test it.

I bought 6 of these fish for my 30 gallon tank over a year ago now. By no means an 'expert' fish keeper at the time i didn't expect to have much luck with them (Especially as they were very very small at the time of purchase). The store owner recommended many 'Cardinal water products' that i declined and i took these fish home and hoped for the best. A year later i have 5 healthy and quite large Cardinal tetra's (i lost 1 within a few days of purchse).
These fish really are beautiful and peaceful. They live happily with my Lemon and Flame tetra and a recently purchased pair of dwarf gourami. The flame tetra often show courting and mating behaviour which seemed to 'excite' the cardinals into courtship and mating behavour themselves. Although i don't intend to breed them - for those who do they seemed most willing to mate whilst they were younger.
All in all i havn't found them anymore difficult to keep than any other fish and have avoided the use of expensive 'Cardinal specific products'.

My silver dollars are about 5 years old and for the last three days one has been laying at the bottom of the tank and his eyes are cloudy looking. He seems to be breathing fast and is very disoriented when I disturb him...swims very fast and hits everything. I don't know what to do to help. I have been putting some melafix in the tank every day but have not done any water changes because I don't want to stress him out. Any advice would be appreciated very much. Thank you.

    Check you water levels and definately do a water change. Do you have good water movement?
  • Cindy - 2012-05-08
    Yes lots of bubbles and the other fish are all doing good. How do I check my water levels?

    What size tank are you starting with?  a 30 gallon is a good started tank. Good starter fish are swords, platies, guppies, mollies and a few other livebearers.  Cool thing about these as you will get a chance to watch them have babies!

I have recently purchased my first fish tank and these guys are not afraid of even my boistrous ramirez! They come right to the front of the tank and get along well with the other fish. I have a shoal of 6 individuals. They must be kept in shoals of at least 5.

    i only have 4 neon tetras left and they seem to be doing ok.....although they seem to take turns kicking one random fish out of the group every now and again.....
  • urmil - 2012-05-14
    I think your neon tetras are pairing off. It's good you can try breeding them if you want

Which they're not. They're family members. At least they are in my family...My heart is breaking for your husband.

In Geogetown Guyana, South America. There are lots of fresh water pond raised fishes by local fish Growers. Tilapia both Red and Grey are very common. Also Pacu fish. Lots of people in Guyana and other caribbean countries, also in most part in South America, China other Asian Countries do not treat Pacu fish as pets but rather briol & baked it as meals. These Pacu is more Red in color rather black.

I was lied to by a pet shop employee that the fish I was buying was as big as it was ever going to get. Two years later I now have only one fish left in my tank and he's the size of half my 55 gal tank. After doing lots of research I found my fish(black pacu)was going to get much bigger. I knew I needed another tank but was confused as to size 200-500 gal? What to feed? So I went to a Man that has owned the longest living captive pacu named buttkiss who is 42 years old and has lived in a 75 gal tank.
He said a 120 gal is big enough for one pacu. So a thank you to Steve Grubel the owner of buttkiss for taking the time to give me the info. I was about to give up on my beloved only fish. Now I'm off to buy my fish(now named buttkiss2) a new tank and I still be able to house my self and butkiss2. Thanks again steve but I'll probably be calling you again to ask how do I get him out of the 55 gal to put him 120 gal? haha

    A 120 gal is not nearly big enough for a pacu. The fish "butkiss" has been in a tiny tank for way too long. I honestly don't know how that fish is still alive. I'm not one of those crazy fish people that think fish are anything but pets or dinner, but you need to know when it gets cruel..... a black pacu needs a massive tank or pond. Don't be fooled.
  • Clint - 2012-02-05
    I totally agree it is cruel to keep a fish that size is a 120 or smaller. I know this for a fact, I have a 2ft long black pacu that I raised from a baby. Its been 10yrs now and he is my Monster and he is a smart one too but I do feel so sorry for him being is a small 120G and I wish so much to find him a New home like a zoo or someone whom has a 1000gallons or more. Problem for me is How do you remove a fish that Big? He is a Foot High, 2ft long a Very Strong. He is eats everything since he grew up with oscars.. He loves talapia and smelt and anything that looks like berries. He love to be hand fed too. Oh and note to anyone wanting one when they get really big like mine they also get really big teeth which love to nawh and rip anything hanging into the water. Ive also gone though alot of heaters too. Good luck

    To MOVE your fish, remembering the weight issue, get two strong outside garbage bags... double bag it, submerge it into the tank, scoot your Pacu into the bag with enough water to cover him up and LUG that sucker out! lol. You can empty him into a holding tank, while he waits for you to fill his new home, or if you are putting him directly in, remember you still need to float the bag to make the temperature the same, unless your thermometer is showing the new tank maybe the same temp or a few degrees higher. Get some help and make sure you have twisted and knotted that bag shut so WHEN he thrashes, you have a good grip on that knot! Getting some help may be the thing to do!

    Give the guy to the national zoo amazonia exibit. They have a school of like 12 pacu with some cichlids and an aropima in a like 8000 gallon tank. I think he would like living there. That goes for buttkiss to.
  • Alex Burleson - 2012-02-13
    It is wonderful to hear, that you as a fish owner have educated yourself in the requirements that the fish needs! Many aquartists, do not take the steps to do so. To remove him from the aquarium, you will need to have the 120 gallon properly set up, and then you will actually have to use a fishing net to remove him from the aquarium. Best of luck!
  • clint - 2012-10-13
    Hey all, Update.. Well it 2012 and I still have My Black Pacu Monster and I still have him in a 120gal. He grew a little longer but actually he got fat and still eating smelt.

    After the eggs are laid, if they are fertile, they will take about 3 - 4 days to hatch.

i have 20 of these great fish in a 90 gallon heavily planted discus tank. They are great schoolers and swim around happily in all areas of the tank. I feed bloodworm, good flake, ciclid bits and shrimp in the tank, mainly because this is the discus diet, but the rummynoses love all of it! Excellent fish i would highly recommend them. Great colour if they are happy.
