I recently bought this bichir and it will not sit flat on the bottom. He swims to the bottom and floats back up. I bought him from another mfker that claims he never did this before but he was doing the same thing in the tub when he got to me. He has eye clout and seems to be filling up with air because I went to net him so I could pull him closer to the front glass to inspect him, he busted a bunch of air bubbles out and was able to sit on the bottom for a short period of time.
I am new to polys and I was wondering if anyone could help me figure out what this is. Thanks in advance for any help.
