Floating Cory

Post by Roberts_Cory »

I have just recently bought 3 Peppered Cories. 2 are fine. the third one can
t stay on the bottom of the tank. he's always floating str8 bak up. I'm thinking he has air stuk in him sumwhere. if so, how can I help him get rid of it? if not, what is it and can I help him? He has no other signs of illness. they are in a 3G qt tank, with no filter, pH 7.5, temp 24*C. I dosed them with a dose of medi (one that turns the water green) but they're now in clean fresh water.

cheers

I would think it is a defect swim bladder. I don't think you can do anything about it. If it were my fish, I'd probably killed it and bought a new one.

There are some swim bladder medications out there in the market - I've not tried them personally, but i still don't think they're effective. Swim bladder disorder is more of an internal illness, so i don't think liquid treatment will be effective.

As what Kim mentioned earlier, there might not be much help for your cory, but maybe try lowering ur pH a lil for ur further batches of corys? keep it the neutral or slightly acidic (ie: 6-7). Usually high pH will trigger stress which may cause further problems down the road, much like a snowball effect.

Sounds like a gas embolism in that cory. What size are they? The fish wouldn't have made it to saleable size with a defective swim bladder, as its quite difficult to be a benthic eater if you can't stay benthic.

Gas embolisms (rather like gas in humans) will often clear themselves. Does the fish have a distended abdomen? You should net the fish out of the aquarium and examine it closely. Are there any marks or distension? As cories will race to the top for a gulp of air as most in the hobby come from O2-poor environs, its possible that something is keeping it from voiding atmospheric air. Put him back in and observe if the fish is able to right itself over the next few days. If not, something is clogging up the works.

Please keep us posted.

They are bout 1/2 inch big. The floating boy, he doesn't have anything that looks odd about him. no bumps spots or anything diff from the other 2.

I'm hoping it is just gas. I put them in an unheated tank as the weather is starting to heat up down here, so hopefully that to will help. He seems like he's staying on the bottom more. Fingers crossed. If he's not ok by 2moz, I'll go swap him :)
