Hi,guys bought a new male black molly from lps two days before,I did every right thing before introducing him into the tank. When the day I introduced him he ate well and gone to all the places all over my tank. But from very next day he started to hangout in a single place that too which is closer to surface nor eating neither swimming but occasionally. I'm worried whether he'll make up or not.He looks healthy no wiggling of body as if some mollys do when they are sick as far as I know. I bought him alone without pair cuz I dont want to keep a fish which breeds every other month. Any advice on him is welcome,I have pair of marble angels and 1 rts along with him.
