I have a single ID shark in a 20 gallon - he has grown to 7 inches and I am now upgrading him to a 55 gallon tank. When he outgrows that I will probably try to make an indoor pond for him =S If I had known how large they get I never would have bought him - stupid fish store employee lied to me when I asked if they got large!!!

    Unfortunately that is very common with these fish.  They are so small at the pet stores and not a lot of people a successful in providing the proper home for these fish to grow and be healthy.  The 55 gallon should last for some time.  Good luck with you big fish!

    I've had one for some years now and he has not grown. From my understanding fish will only grow to the size of the aquarium and not bigger. Mine has always been about 7' long!

    The tank is a bit too small.  They need at least 100 gallons to start and even that big tank will need upgrading to over 300 gallons.  It really needs more of a variety of foods.  In the home aquarium they will generally eat all kinds of live, fresh, flake and pellet foods. These fish must have a balanced diet of green and meaty foods. To keep a good balance give them a high quality flake or pellet food two to three times daily, but give them only what they can consume within 5-10 minutes. Also feed brine shrimp (either live or frozen) or blood worms. You can supplement with live foods such as feeder fish, which have been quarantined and fed proper food, to gain excellent nutritional value. Additionally, these fish will accept live crickets, or worms.

These fish may not be venomous but their spines have some toxin. I got stung yesterday by one and it was very unpleasant. Handle with care.

Hello everyone, I just bought an Albino ID @ 3 inches long.  I originally put him in my 100Gallon but had to take him out because he got stuck under ornaments and I was afraid he would get sucked into my filter. I have him in a small 15 Gal right now until he gets big to safely be put back into the big aquarium. My concern is now that I see some raised spots on his side and he's getting reddish and not swimming much. What should I do? I have experience with his breed too. I have a 15 inch ID in my large aquarium. Any Advise is welcome folks.

    Not good.  I would check out the information on Animal Worlds fish Disease and Symptoms and look up the symptoms your guy has and the recommended treatment is on the side.  Sounds like red pest which is a bacterial disease and curable.

If my iridescent shark was to get big, could I put him in a big pond with other fish like bass,sun fish,catfish,and frogs? or would he die?

We have just bought a Pegasius. At the moment it is in a tank, when it gets bigger would it survive in the really cold water of my pond, which could get down to 2 degrees C.

    These are not a cold water fish. It would not last in a cold pond unfortunately. Many other choices out there that will.

Does anybody know what size they mature at ?

  • Jeremy Roche - 2012-02-29
    The PGMA states a mature specimen will be 1.5 kilograms.
  • Charlie Roche - 2012-03-05
    At maturity they will go over 3 feet - estimated 39 inches long. That is a big fish.
  • Rameres Jr Cumba - 2012-03-05
    So how big would it be? In inches
Rameres Jr Cumba - 2012-02-29
I would mostly recommend these some what peaceful fish to those with access to large tank or pond due to their skittish behaviour at times, but they are still wonderful fish to own if properly cared for.

    Pangasius Catfish are rather nervous, though friendly fish. The cichlids you have are moderately aggressive, and being already established in the tank, may have viewed the introduction of these new inhabitants as an intruders. For the best success in mixing fish with different temperaments is to add the more aggressive fish last. If you have a large tank, you can try rearranging the decor to upset the established territories of the existing fish. Also, in addition to rearranging the tank, taking the existing fish out for a few hours and letting the new fish get comfortable may help.
  • Tristan - 2012-02-29
    I have kept the pangasius catfish with the fire mouth cichlid for 4 days in the tank by themselves for 4 days and rearranged the tank furniture around. Am i able to add the other aggresive cichlids to the tank?

Hi, I purchased 2 catfish about a week ago. When they were both netted out in the shop I noticed 1 of them looked really blood streaked. The assistant just said it was stress but it hasn't got any better. I have noticed that it looks really fat like it's pregnant. It's just really pink and red looking especially round about its fins. Can anybody help me out if they think they know what it could be??? thanks.
