This is a nice fish, but it does not swim around much. It seems to spend all of its time trying to swim out of the aquarium. I find it hard to feed because it does not come right away.

    The Pangasius Catfish doesn't just hang out on the bottom bottom like most catfishes, but rather occupies the middle of the aquarium. They are constantly on the move and will occasionally go to the surface for air. These guys also stress out at times if you tap on the tank or with suden movements etc. Could you be tapping on the side of the tank or splashing which would make him want to jump out or appear to jump out. They do come to the surface for air.

I NEED HELP/ADVICE DESPERATELY! I have 2 pangasius catfish that are about 3 months old and almost 3-4 inches long. I thought I injured the bigger one when I was tryin to catch my gold fish that are in the same tank last week and maybe I hit him. He has a large white fungus looking growth now that's almost like bubbling. He's been ok up until tonight but he is lieing at the bottom barely moving. What can I do?!!! plz help email me My mom has some pills for her pond outside that are for some sort of fish illness. They are capsuls. I think I am going to try and find them and use them before he dies. Plz help.

    There is an article on Animal World where you just posted your question that is called Fish Diseases and Symmptoms. Just go to any fish article and scroll down till you see it and click onit. One the bottom of the Fish Disease and Symptom article there is a bunch of symptoms. Determine what it is you believe your fish has and use the recommended treatment prescribed.

    If the spots look white and salty it is probably ich which you treat with an antibiotic.

    Grey or white fluffy opatches ia a fungus and you treat with an anti fungal.


    The article is clear so just go back to your fish and click on Fish Diseases and Symptoms and you should have an answer. I tried to attach the article but for some reason, it wouldn't work. I am sorry

    Good luck

I have recently bought 2 pangasius catfish and have read up on them only to find that some websites say that they don't like having the tank light on, and some say they love it! I'm confused.

    Hi Claire. I got 3 babies. One the fish man at the shop said it would take 3 years to get bigger. I got them in a 3 foot fish tank. I'm waiting to move to a ground floor falt where I can get a bigger tank, 6 foot by 2 foot by 2 trying to hit 2 birds with one stone. So I don't have to give them back to the shop but if I have to just have to wait till I move and get them again? Let me know as well if they do better with the light on thanks.

We have two Pangasius Catfish. We have had them for a few years now - watched them grow from 3 to 20 inches. Every once in a while, the larger one gets his "nostrils" inflamed. They get really large and red. We haven't been able to figure out what triggers that and how to heal it. Can anyone help? Thanks!

I was changing my tanks water and when I took one of the catfish out to put it in the tote, its fin got tangled in the net and I had to cut it a piece of the net off and there is still a piece stuck on and I can't get it off.
What should I do?

    Did you get it off? If not can't you just hold it out for the few seconds and use a cuticle scissor to cut it off. Just be careful. You really don't want other fish or that fish trying to chew it off - not that I would think. Cuticle scissors should be able to slide right underneath the piece of netting without endngering the fin of the fish.

    I have the same thing and I realized today that my koi is doing it cause the water is not clean.

    When they get frightened they play dead or swim really fast and hit themselves on the tank.

    They tend to play dead if they are stressed.

Alright I know that everyone loves their "Id shark," I however do not. I thought that maybe you would like a comment on a different level. I adopted a large tank with 3 of these sharks in it and some other lonesome kind of fish. The sharks were smaller but they are now about a foot long. I HATE them! The biggest one is friendly and calm but the other two where crazy. Sometimes there is nothing around and nothing going on and they will freak out and flip around, bang into all the other aqua life and walls. They bang into the filter systems and heater and all that stuff and then your constantly making sure that everything is alright. And then when they are done freaking out they look like they are dead and that is probably the best time that you can have in that tank. I have even tried moving them to a room with no traffic and they still freak out. They seem to get sick lots but all the other fish in the tank and healthy and happy as long as the sharks arent acting like jerks. One shark finally died after not taking to a treatment for one month. I dont know how anyone can say that these sharks are good pets. This is the worst adoption that has ever happened in the history of animal adoption! I hope they dont have a very long life span.

    Why don't you sell them then put them in the paper?

    When people love their pet, they love them. These ID sharks grow big but the have lots of personality. You should rescue the dieing shark Martina.

I have had my shark for about 2 months now and for about two weeks he started acting different. Now he is running into everything and swimming in circles. I put my hand in the tank and her ran into it. I have been watching him and I don't think he can see. I feel bad for him but I don't know what to do?

hi there, all my 4 yr old wanted for xmas was a shark so i got a 30glln tank and 2 bala and 1 id shark. my id sits in a tunnel we have and hardly ever leaves unless there is food of course. i actually thought he was dead, he floats on his back and stands straight up on his tail and i think he must have hit his head really hard because he is fine now. i am going to get a bigger tank and a few more to keep him company, i just feel bad because he always seems so depressed or he is just really lazy. he had a huge belly for a month, thought he was pregnant, and all of a sudden it was all gone. i don't get it but he still seems healthy. hasn't grown much yet thank god. love shrimp. enjoy your sharks they are awesome

    A 30 gal is far to small for those 3 fish, and normally balas are not supposed to go with id sharks. You really should leave id sharks alone and try not to spook them. They're very sensitive for they don't see well.

    Hey there wondering if some kind people could help me out here. I've adopted 2 Massive pangasius will post pics later on. Not sure of the sexes and not sure best way to feed them. One was injured in a rock in a tank way too small for them hence they came here to my bigger tank. I've never had a mature pangasuis had a few youngsters that fell victim to the cichlids they'd lived with for months got rid of the cichlids and they live with 2 tinfoil barbs that are fairly big a 6 to 8 inch plec and a similar size black ghost knifefish. They appear pretty chilled and happy after the war we had getting them out of a box into the tank no fights between them. I tried the pellet food but they won't eat it and they will eat tropical flakes but I've read that's not enough for them so any help much appreciated.

I have 2 id sharks and I went to check on them today and noticed their skin looked this I mean white, red and some peeling off...almost looks like a chemical burn...has anyone had this before? My water all tests good...I did add a couple fish and a little bit of ick medication but not much for a 170 gallon tank. Any ideas how to fix the problem?

    My Pangasius catfish is the same right now, and the skin is peeling off the top of its head and back. I am so scared I had it for over a year and a half and this never happened before.
    Though he was in the same tank as a sodonitis catfish which is think hurt it because sodoni is poisonous and swims upside down and would chase my shark around. So I got sodoni out but sharky not feeling better.
    If you find a solution let me know.
  • Ken Finnell - 2011-02-19
    Same issue with my catfish, Looks like a burn or skin peeling. I did have him in the same tank as my upside down catfish as well but he was moved before this even happened. I originally thought it was from my heater like a burn, then looked at it like it could have happened from him running into the coral. The only thing I've done different was add some ick because I saw his eyes were getting white in the front top areas. Now this happens... I think the Ick is causing it. Going to do a 50% water change this week and follow up with a 50% water change the week after just in case.
