I need to stop getting my crickets at Petco. I went in with the simple agenda of feeding my tarantulas. They had a bunch of bettas in and many of them were in dirty water and poor shape. I wanted to take them all home. I didn't but I did take home two which I was to get at a reduced price after talking with the manager so I feel that I can call them rescues.
First is this red dragon plakat. He doesn't seem to be seriously sick just cramped and stressed. His fins are kind of clamped. Hopefully with some TLC he'll be feeling good soon.
And here is the really sick guy. He is a purple and red fish of indeterminate tail type. With serious finrot and swim bladder problems.
He can't swim down. He will try and then as soon as he stops struggling he pops back up and lists over on his side. And you can see that most of his caudal is gone. I have him in a two gallon kritter keeper. 1/2 full with silk plants for him to rest on and am treating with aquarium salt and half strength melafix. He will also get daily water changes.
The good news is he wants to swim around and appears to have some interest in living so hopefully with a little help that will happen.
