Planted 29 gal
Got a fancy male guppy laying at bottom of tank on gravel.
Tank mates are other male guppies, endlers, neons, zebra danios & an Otto.
Everyone else is fine. Tank has been up 6 months
PH 7.8, 0,0,0. 79 degrees. I moved him to a quarantine tank.
I have meds inc salt, want to have some idea what I'm treating for.
Lays on bottom of tank but if I nudge him, he swims all over for 20 seconds & lays back on bottom. Not eating either.
