So I've had this red headed solon wrasse for about a month. I ordered him online, and when I got him he didn't look good. He sat at the bottom of qt for two days without moving. Then he began swimming around about half the time and resting the other half. After about a week he seemed healthy enough to me (was eating well and I thought with the extra space he'd start swimming). But he still rests on the bottom of the tank most of the time; he only comes out to eat. I'm not familiar with wrasse movement but his swimming pattern looks very labored to me. His stomach looked a bit pinched so I fed him more, now his stomach seems fine but his behavior continues on. Ammonia/nitrites are 0, salinity is 1.025, ph is 8, and nitrates are 20. Please tell me if this is normal wrasse behavior or not, because I feel like it's not. My tank is 50 gal. Tanks mates are a flame angel, pair of clowns, and a dwarf eel.
