PostSubject: pangasius not eating   Sun Jul 26, 2009 10:56 pm

now its about 2 months since i got my tank...
and from the last 3 days, my 2 pangasius sharks haven't been eating anything. all the other fish seem to be ok, eating healthily etc
but both these guys are swimming at full speed around the tank, yet not wanting any food. could they have some sort of internal infection or is it normal? they look perfect from the outside.

Hiya wave Can I just make sure that you are talking about the Pangasius Catfish shark (also known as Iridescent shark)?

Sorry to ask a stupid question, but how do you know they are not eating? I have just been reading up on these fish as I know nothing about them, but from what I have read, they will eat anything (including their tankmates) food left by other fish as well as that put in especially for them.

From what I have read they get to be VERY large (up to 4ft in length!!!!) and need to be kept in a huge aquarium. The stuff I read all said that they are unsuitable for home aquariums and that people who have them and didn't realise just how big they can get to should return them to their local pet store. Apparently they do not thrive when they are smaller unless they are kept in groups.

The only other thing I found out is that they can be a very nervous fish and if they get startled may dash around the tank and unjure themselves on ornaments or even the side of the glass etc. They may then 'play dead' till they recover!

I would have a rethink about keeping these fish and replace them with something that isn't ging to grow to the size of a small car! Shocked

they may be stressed and not eating or simply finding food and not eating when your watching

any number of things could be going on - the problem with treating with meds 'just in case' style - you may be treating something or not treating anything - but most meds are somewhat 'nasty' to fish and you dont really want to trewat them if its not necessry.

Id simply keep the whole tank hungry for a few days (2 days) then feed something you know the sharks dont normally resist - if they eat then fine - if not well plan b

in the meantime - id seriously think about rehoming them anyway

thx Smile

both of them grew about 1.5 inches in the last 2 months

if they do indeed grow too big then i'll have to re-home them someplace (most probably will happen in the next few months or so)

lol

i have them in a tiny tank at the moment, not as tiny as a biOrb though.

i know they will eventually grow VERY big
but atm they are "babies" (that is less than a year old) so theyre only about 5 inches each.
i doubt that they actually grow to 4 ft in captivity- maybe in the wild they do

people believe fish only grow to the size the tank they are in will allow

this is true in one way - and thats the outer body stops growing - but the internal organs carry on growing and thus they get crushed and the fish is obviously damaged as a result

tbh - I would say to rehome them as soon as you can

as soon as i find a tank that's big enough Smile
and of course a person who's willing to take them. not many people say yes to a fish that's going to be that big in a few years' time
