    Yes. The shark swims in the middle of the tank and the lobster hides most of the day. I have them in the same tank and haven't had a single problem. They get along perfectly fine.

Hi....I have a pond at home (approx 12feet X 8feet X 2.5feet deep). I have 6 red carps (four are 14 inches length and the other two are apprx 8inches). 2 months ago my neighborhood petshop guy told me that one of his clients had given him a 16 inch ID shark since it was too large for his aquarium. I brought that irid home and put it in my tank/pond ..... all seems fine as the irid is doing great and has taken well to the new habitat. I am wondering if there is a possibility of the irid causing harm to the smaller red carps ??

    Nice size pond. I doubt the Irid will cause any problems as it is a pretty shy fish. The carp, which are peaceful too, are actually the ones that would be the most likely to be pushy as they are social, active... and love to get to the food. But I don't think you'll have problems with any of them, you offer plenty of space for all.

Our pangasius catfish has a big red sore on his nose. We have tried treating for common diseases with no luck. Does anyone know what this could be? His other nostril is fine and the other pangasius catfish is not showing any signs either. I'm not sure where to turn.

    My irrodescent gets spooked really easily and bangs his face off the glass constantly. Maybe that could be it ?

    It has maybe banged itself off the glass at night. They easily get spooked. Should heal itself but try adding a tablespoon of table salt. This will act as an antibacterial agent and clean out the sore.

Im one of these people that have let tropical fish take over my life, I live for my fish. I take a particular interest in catfish. I've been reading the comments on Pangasius, this fish should not be sold in pet shops to people who do not realise their full potential. I have a tank measuring 9x3x3.5 and a 20,000 litre heated pond in the conservatory. My largest pangasius in nearly 3 feet long and weighs approx 26lbs. I have 6 in total, they were all cast offs from people who could no longer keep them due to size. In my opinion any animal,(whatever it is) that you buy, you should be able to look after it for the whole of its life. A lot of catfish like Pangasius, Shovel nose, Red tails, Giraffe cats, there's too many to list, but these are frequently available at fish stores from 2" to 6" and look lovely. But they won't tell you, you have a monster on your hands, some like Red Tails will eat most your tank when you get it home. I decided I wanted to KEEP these beautiful fish, so I bought and Built some huge tanks to be able to enjoy them for all their lives. (Recommend building as it's cheaper). If your not prepared to do this then just steer clear, don't waste yor time or money. Above all always research any fish your not sure about before you purchase it. Any fish I see or am offered for whatever reason, if I don't know details about it, I will always go and find out for myself and not take other peoples word for it. I suggest everyone does this. Also, people will tell you their max size in the wild. They seldom reach wild sizes in captivity, that doesn't mean a 6 foot Catfish will only grow 6 inches, it'll probably get to around 3.5 feet, so a little common sense is needed. Happy Fish Keeping.

    Hi, I have got a Pangasius Catfish. I was told it would grow to within the size of my tank which is 80 Ltrs. But it is now too big and must be re-homed. I agree pet shops should be better informed and not sell these fish unless people are aware of the size tank they require. I am currently looking to find a suitable home for it...

I have an Iridescent Shark who has died twice before. The electricity went off and so did the heater. By morning the water was very cold and the fish was belly up and not moving. We went to bury him when we noticed his breathing. After an hour of the power coming back on he was swimming around like nothing happened. Is it normal for my fish to do this?

    Sounds like you have a very durable fish. And it sounds like it's 'normal' for him:)

    When moving we had the same thing happen. I turned the power off in the house overnight, forgetting about the fish tank. The fish was belly up for many hours. I told my wife to add hot water to the aquarium before she buried it when she called and told me the fish was dead. It is a year later and it is still happy fish.

I had a iredecent in a 30 gallon grow out he was about 1-2 in long also I kept him here because he was very lethargic. He would swim about a few inches then just sink to the bottom and lay on his side. I saw some ich on him so I raised the temp to 80 degrees f and then treated half strength with ich treatment. but he was still lethargic. I had plenty of live plants around the back and sides of the aquarium and loads of small live plants for him to rest in. I also had about 6 corys because he was a messy eater. lol thnx

    Be careful what medicine you treat your fish with. Some of these are deadly and will kill the fish. Always read the ingredients on the bottle carefully.

    I have an iridescent shark in a 45 gallon tank. He just lies on the bottom and once in a while he will swim in a circle real fast. Then he will lie on the bottom again, sometimes on his side. This has been going on for a month or more. It looks like he is dying and then he moves. I do not see signs of ich, but the guy at the pet store said fin rot. I have medicine for that. It says to treat 7 days, I have treated 4 days so far and do not see any sign of improvement. The other fish in the tank do not bother him. Any suggestions?

I have 6 pangasius, My largest one is 6 and a half feet and that is just under a year. I keep mine in a 9000 gallon aquarium with many other massive fish like a 2 foot balance shark.

I am rehabing two irradescent sharks that were left behind by a frinds renter. The fish had been placed in a garbage can outside. I have managed to rid them of fungus and their wounds are healing but I have not found any food they seem to eat. They are presently in a 500 gallon tank but I do not want to keep them. One is about a foot and the onther is about one and one half feet long. If you have any ideas to relocate these fish other than serving them on a plate please let me know.

    Try visiting a local pet store. They usually are very helpful and will have customers that could take these fish. I don't know about mass merchant types of pet stores, but locals are usually really helpful:)
