i adopted a juvie goldie yesterday, all seems ok till this morning.
he was floating vertically, den swam normally a bit, den float again. wasnt breathing heavily.
when i wanted to catch him to put him into a hospital tank, he swam very fast (normally) to avoid the net.

could this be swim bladder issue?
i fed them (2 of them in 1 tank) a bit of bbs this morning. he din really eat, was bz floating away.

ps: how do i post video here?
