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.

    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.

And they are excellent eating! They are growing rapidly as a food fish in Asia, because they have very low oxygen needs and can tolerate stocking densities that lesser fish cannot. They are seeing exports around the world in record numbers. Bad news for the American catfish farmer, unless he gets on the Pangasisu wagon pretty soon.

Hi, i have a Pangasius Catfish for over 10 years now and he's like a buddy to me all these years. Unfortunately, he developed mouth fungus and I have no idea how to treat the disease. The instruction I got here is too complicated for me. I'm so worried it could kill him because it grew bigger above his mouth, I can only imagine how it could be painful for him and all coz it's kind of swollen. Is it okay if I treat it with Methyline Blue 1tsp a day? Problem is, he lives with other small fish in the tank, is it safe to do that? We don't have specially stores around or vets for fish here coz I live in an island somewhere in the Philippines. I wish you could help me with some simple yet effective treatment tips, I would thoroughly appreciate it. Thanks so much... Love and respect!

    I've used Melafix foe years ..(Drs. is used for scaleless fish and seems to work well for almost every disease I've encountered.. even though I have not encountered the one you are speaking of...I have two 4 year is about 15 inches and the other about 7 inches...I just recently moved (about 4 months ago) and bought a 46 bow front..upgrade from 30 larger one was ill all of the time due to close confinement and the filter not working properly because of his size...I think this might help.. hope sincerely so..
