Animal Stories - Silver-tipped Shark


Animal-World Information about: Silver-tipped Shark

   Though this is a very attractive fish and fun to observe, the Silver-tipped Shark or Shark Catfish gets rather large, up to 14 inches (36 cm) and needs several companions. This equates to a rather large aquarium!

I have 2 of these and 1 has just started to go swimming around the tank non stop for the last day or so which is out of the ordinary for this breed of catfish shark. Checked PH GH KH AMONIA & NITRATES which are fine. Can anyone tell me what is going on with the fish and a cure for what maybe the start of some disease??????
Many thanx

My shark catfish has started to hide and chase other fish if they come to close. He also appears to keep gulping. I'm wondering if he is likely to be brooding?? Any tips?? I have read that this is pretty unlikely for them to breed in captivity... But wondering what else would cause this behavior?
I have 5 shark catfish in 180L tropical tank x

    Hi, I know this reply is very late but the first thing I would do is test the water. Your ammonia and/or nitrites might be high. Definetely a water change would be in order. Also, I learned that almost all bacterial and fungal infections are secondary to a parasitic infection. At the first sign of illness I treat my tank with 'Quick Cure' and add a little additional aquarium salt. The salt provides them things necessary for their immune system to fight it off. After that I do a 7 day course of melafix. It's natural and cures secondary bacterial infections and helps any damaged fins/scales to re-grow. Pimafix is also a secondary treatment for fungal infections. My fish have not tolerated it well but it has been highly recommended to me by many people and I keep some on hand. Hope this helps for the future.

I purchased two of these beautiful fish at PetSmart and they died within ten days. The girl in the fish department did not know anything
about them at all. I realize now that the water for my angel fish is too soft for these sharks.
Does anyone have suggestions about similar sharks thsat would stay smaller and go better in a soft water environment?

Do silver tip sharks NEED brackish or saltwater as they get older or is it possible for them to survive in fresh water their whole lives?

    Silver Tip sharks are actually brackish water and in the Animal World Article Silver Tip tells you how to do that.
  • Katie - 2012-01-08
    Yes silvertip sharks do need brackish water as juveniles they can survive in freshwater but it is best to keep them in a brackish tank with a salt content of 1.005 and this should be increased gradually to 1.015 or above as adults this is for their long term health.

My shark has suddenly developed a white body fungus and appears distressed. What medications are safe for this species along with botias and red-tailed sharks?

    Sounds like a fungus to me. Here is a link for Fish Diseases and Treatments so just scroll down to symptoms and they are clear and the recommended treatment is there. http://animal-world.com/encyclo/fresh/information/Diseases.htm

    Thanks Charlie. I had always learned to be a bit cautious treating scaleless fish like sharks and loaches, but apparently that's "old school". Unfortunately my white tip succomed last night but I still need to protect the rest of my tank. What ever it was attacked quickly and ruthlessly. You'd think after 40+ years of being a breeder and avid hobbiest I'd know better. SM

    I've done birds for years and years and sometimes something happens that I just can't figure out. Weird. I am sorry your little fella went though.

Hello, I love these fish, but they will not eat! Anything seemingly, whether it be tropical flakes or Blood worms. Any suggestions or alternate sources of food I should try??

    Pellet?
  • Timika - 2011-07-29
    Try sinking pellets. Mine wait for them to get soggy and then suck them right in their mouth.
  • ryan - 2011-09-01
    Try neon tetras they ate mine all six
  • Alainn - 2011-09-04
    Mine love the freeze dried brine shrimp. And I have a few plants that float on top of the water and I sprinkle the shrimp the sharks seem to enjoy hunting in the plants. gl hope this helps.
  • Charles - 2011-09-09
    Try ghost shrimp, I have four of them and they love it when I feed them ghost shrimp, they will actually chase them all around my tank.

    90 gal tank, 4 cichlids, 3 silver tipped sharks, 1 Placo, 1 (not sure of the name, but fat little orange and black guy that grunts when he is out of the water)

We have had a grand total of 4 of these awesome little guys, and only 1 has survived (so far!). One we had in our 40G long with our cichlids, and 3 in a 55G L with emperor tetras, rasbora hets, and angels. So far, all but one in the big tank has died. My husband LOVES these guys, and I agree that they are cool and interesting to watch around the tank. They don't seem to die of any disease, or because of our water levels (we have yet to lose a fish due to our errors). They just randomly up and die. Any suggestions would be greatly appreciated, as we sincerely adore this fish, and the money we keep spending on them!

    There is usally a reason for things. Did you get them all at the same time? Did you get them from the same place? Attached is some information on the silver-tipped shark. Read the info and if you have additional questions, I'll get you to the owners here cuz they have a trillion years on fish. OK?
  • floyd - 2011-09-08
    They need to be in a brakish tank they are dieing because of this. They will not eat because of lack of salt in the water quality and die slowly.

    It isn't normal for silver tipped sharks to just go back and forth on the surface. Now what I don't know is how long it takes them to acclimate to a new tank. Also, if fish are behaving unusually, it is usually the tank conditions. Check your temperature and PH etc. Filter working? This is a link on U-tube which I thought might be of interest to you.
    http://www.youtube.com/watch?v=QMuV0Z-f7TQ If you go to U-tube and enter silver tipped shark you will see how the silver tip normally swims around. There are several videos. I thought the hand feeding was awesome. Animal World Article on Fish Disease and treatment which includes behavior issues may help also. Check Diseases and Symptoms and treatment is recommended. Probably tank conditions though. http://animal-world.com/encyclo/fresh/information/Diseases.htm

I wish I had stopped by this site before I bought my silver tipped shark. While at PetCo, the girl assisting me told me that this shark only grows to be about 12inches long, not 24. I also got 2 yellow guppies, and she never mentioned that they may end up being like feeders. I think it's interesting that there are so many comments about how the little fish will become food for this kind of shark. It's completely true that when the lights go out, your little fish go missing. Only 2 days later, and both my guppies are gone. Thanks for having a really well maintained site, as I now have a better understanding of my shark. ^_^

    So true and not knowing how these fish are, I end up learning the hard way!

    Every morning, I notice some fish are gone... until lately that I finally woke up and used my head. I only have one silvertip for about 3-4 months now and grown up to 5 inch's. As mad as I am, I have to admit, they're beautiful fish and mine has so far taken about 30 small fish ( guppies, neon's, mollies, medium various tetras,...). Yesterday, I put him in my small tank till I decide whether I should give him/her away or what. I wish I knew what to do!

    12 is the more likely length for them lol the people at the pet store don't always know every thing don't flame them.

I just got two silver-tipped sharks yesterday and a pictus catfish. I have them in a 10 gallon tank which I am just figuring out is too small for when they start to grow. I dont really know anything about them, the walmart associate didn't know anything, he told me a 10 gallon would be fine for my fish when they're full grown but I'm finding out now that it won't be. Are they salt water fish? Is there anything I need to know about them?

    No these are not saltwater fish, however they technically are brackish water fish - meaning they would do best with some salt added to the water. 1-1.25 teaspoons of non-iodized salt is recommended to be added to the water. And yes, a 10 gallon aquarium will not be sufficient when they are full-grown. As a general rule, you will need 1 gallon for every 1 inch of fish. But you will usually need more for larger fish. With two full-grown silver-tipped sharks, you will need a minimum of a 60 gallon once they are grown, but more would be better, especially with another pictus cat and other fish that may be added as well. I wouldn't say you need to go out and buy a larger aquarium right this instant, but it is something you would want to plan for down the road.
