My wife and I just bought two Pangasius Catfish. Each about 7 inches. The aquarium that sold it warned me that they grew big. How big, I didn't realize until I researched on the web. Now, I am WORRIED!!!. Planning to build a HUGE pond for them. Would be fun to have a huge fish. My tank is 4L X 2W X 1H. I have a water circulator, so they seem very happy. Looking forward to the experience. My thanks to web sites that carry information. (Sri Lanka)

I have two iridescent sharks 13 and 15 yrs old, 12 and 14 in. long. I have had them forever! They had outgrown their 55 gal tank and I tried to re-home them but after getting them into a new home my husband and I realized we did not want to give them up. So we went to our new friend and got our fish back, replaced them in their 55 gal tank and went shopping. They developed stress related ich which we treated with melafix in the 55 gal tank while we set up their new home. About three weeks later on Christmas morning they got their present and were moved into their new home. They got stressed and again had to be treated for ich. They were fine for about a week after that but then the smaller shark Achilles began to fade from dark gray to a very pale gray and developed a yellow coloring behind the eyes and on the fins. The water has been tested only slightly high in ammonia we are adding bacteria but the yellow coloring has lasted 10 days now. They eat fine and are active as always, I don't if the gender of either but they have always gotten along fine. Anyone ever see this yellow coloring before?

    Thank you Toby for your input. We are trying. Some days Achilles, named after my attempt at re-homing because he/she was bitten on the tail by the resident jack dempsey even tho it was much smaller, seems to be re-gaining the normal dark gray color. I couldn't help hope/wonder if the yellow coloring had anything to do with mating. Last night and today I have noticed a new behavior, Achilles swims under Hercules and nudges with his head. It does not appear an aggressive move, guess I will just have to wait and see.

    yes it will take a while for it to go away my shark had it well both one died but the other lived it will be fine if not go to the petstore you bought it at and ask what is happening hope they feel better(:

    Well, so far Achilles and Hercules are fine. Achilles still has some yellow tint to his fins and the yellowish color behind both eyes but is a little darker gray again. Still not as dark as Hercules, or as dark as he was before the move, but both are very active and eating very well. We have moved all of the tank mates from the 55 gal. to the 150 gal. everyone is happy. And now we get to go and buymore fish for the 55 gal but not ones that get too big this time. (:

Recently my husband bought home a 8 inch pengasius from a local petstore that had him in a 10 gal tank. The fish had been there for about a week because the owner couldn't care for him any longer. My hubby took pity on his sweet soul. He hasn't eaten for the first three days we had him and is very thin. My hubby had to force feed him gently. We are hoping he will be ok. He doesn't bang around the tank and he isn't as shy as some pengasius have been described here. He likes to hang out on the side of our tank. We bought him two little pengasius friends hoping they might school together and help him to feel more comfortable. Anyone have any suggestions for us, either regarding forcefeeding or how to help him want to eat. We are really trying and hoping we can save this beautiful creature.

    It normally takes a new feish a few days to acclimate to his new surroundings. It is sorta like the cat hiding in the closet or under the bed when you first move. If he wasn't sick then he should come around in a few days. Good luck and sounds like you are doing good.

    make sure you are willing to own quite a large tank for them
  • Anonymous - 2012-01-13
    Yeah you need a huge tank when they are full grown. They will be about 3 or 4 feet. In the wild they get to 6 to 7 feet. I would say 800 gallons and up or a pond

I have an Iridescent Shark Catfish in a 90 gallon tank. I have raised the fish since it was a baby and now he is about 12 years old. He comes with tank and is any one interested in adoption of a 2 feet long catfish?

Hi! I'm Roy of Philippines and I just got back to fish keeping again a few weeks ago to save 2 pairs of id sharks (2 blacks 16-20 in and 2 albs of 8-10 in) from my neighbors small outdoor pond. The black male I'd got his right fin stripped as well as a lip bruise-more from the net he used to catch. They're finally settled happily outdoor in a shaded aluminum tank of about 250 gals ...need more info though re my black female laying eggs. Will it be safe with the smaller id albs? What's my chance of bringing these eggs up successfully given the said situation? Needless to say my bottom tank got pebbles and stones that these eggs could be hidden but still...?

    General rule - if one fish can fit the other in his mouth - he will. Babies - you sound like you have been through this before. I honestly hope there is someone on this site that has done this but either way - you won'tknow unless you try. Good luck to you.

    After you see the eggs, remove them from all the other fishes at all costs because they will most certainly be eaten. And the chances of hatching the fry is 50-50,but still try.

I have 7 of these fish. They range in size from just under a foot . To almost a meter long ! They are in a large outdoor pond which is oval shaped so they don't panic and flip out . I tried moving some smaller ones into a another large pond which was rectangular and
the would jump out almost every day. Luckily I was around at that time and because they can survive out of water for longer than most fish they were ok. They are housed with 5 red eared sliders ( terrapins ) and 3 common plecos. Very peaceful fish and all get along well.

    Hi John
    I have 2 pangasius fish they are over 20 years old, I would like to know what heating you use in outdoor pond or are you in a hot country?

    I love hearing that people are doing so well with these fish. For some reason, they always die on me. I've done everything. I love their personalities but don't know what to do. Any advice?
Alejandro Faz - 2011-06-07
Would anybody like to trade fishes? I have some pangasius catfish and I really don't like them. They get spooked very often so if you got any other fishes more better then these hit me up.
