HI. I purchased a silver black stripped irridecent shark for my daughter and i'm starting to think maybe it was a huge huge huge mistake. A-I find it isn't doing well in a community tank and B. I need to go purchase a MUCH MUCH bigger tank.
For the last few months I've noticed this shark loves looking at itself in the reflection of the fish tank. Then a couple days later its stomach is gets bloated. And I mean to the point where it looks like its going to explode. And then you just get up one morning and go to the fishtank and it looks healthy again. Whats going on with this shark

Is it making eggs and then reabsorbing them or something
PLEASE LET ME KNOW!!
