ID Shark help.

First off please dont lecture me on ID sharks as yes I was new to the hobby, live and learn etc etc. Sadly I do have two of them tho, very small still.

The problem I have is the smaller one keeps swimming on the surface like he is to boyant and has to almost force swim below the water. I have also noticed when I first got them they would go crazy for flakes now I hardley ever see them eat but they still young! Biggest one is maybe 5 cm. Ive tried researching bloat and swim bladder and heard flakes could cause fish to float but was just wondering if anyone has any ideas what the prob could be and what I should feed them if not flakes. The bigger shark is fine and looks very healthy tho I dont see him eat either. Dunno if he eats the bottom pellets when I turn the lights out.

Thanks guys and gals.

 

It looks like a Pangasius to me. Right @Willem ?

If I'm correct, then you should know that they get very big.

 

as far as I am aware a Pangasius is an ID Shark. Please feel free to correct me on that though as I may have my facts wrong.

 

Try feed bloodworm, not a staple diet of flakes. Bloodworm every third day or even a feeder fish like a white cloud.
And yes, it's a pangasius.
@gdt78 in your defense, I also thought this was a shark identification.

 

@Firefly. Thank you for your help. I will deffinately try this. I bought some brine shrimp but they not interested in that either.

 

@CharlieB That Pangasius has a huge stomache as if it has just scoffed itself!

Am I correct in saying that you have not seen the fish eat for a while? Perhaps it is constipated.

 

Sorry I just clicked what you guys mean! I should have written Iridescent shark in stead of ID. apologies for that :embarrest:

 

From what you have described it sounds like a swim bladder problem.

 

Yip that one looks like a balloon try and feed it some boiled peas or one that acts as a laxative or try some baby marrow
soffend in boiling water for a couple of seconds

@gdt78 I went to pic up a mate for sharky yesterday very battered and brused and blind in the one eye already got him in the meds and his looking better all ready

 

Good job Willem, Cant wait for that new tank of yours to be build ...
