I have 4 D.leucomelas, I have had them for a little over a year now, all live well in a 20 gallon tank. 2 days ago i noticed 1 looked a little thin, he was slow to react and moved very slugish. today i found him floating in his water fall. I guessed he was dead at first, and took him out of the tank but i could feel his heart beating barly in my palm, he barly moved his legs a little after some time. I have no idea how long he was in the water i have reason to believe he might have been to week to climb out on his own. he is currently alive - but in very very poor shape. I also noticed another 1 acting a little slugish today(from the same family) anyone have any idea's? I really like him and would like to keep him in good health.
