I bought this Rainbow Shark a few days ago and I put it in my 20-30 gal tank with Zebra Danios, Red Platies, Guppies and a few small Tetras. I have this temple shaped decor which the rainbow shark loves to hide in all day, I was wondering if its tankmates may cause problems and if it is ok for it to hide in there all day? and the rainbow shark doesn't eat when the other fishes eat and I would like to know if this is a problem? Thank You
