I have a 75 gallon tank with a variety of glofish (5 danios and 2 rainbow sharks), 4 yoyo loaches, and 4 striped kuhli loaches. The water quality is good and filtration includes an fx4 and a pennplax 1000 canister that runs through a UV inline. Two air stones and a Fluval UV3 internal filter to assist with water rotation. Hopefully that info is helpful, if not I apologize...
Anyways, one of my glofish sharks seems to have found its preferred resting place, sucked up to the fx4s intake. It shows no signs of illness or anything out of the ordinary and quickly snaps to attention if I tap the glass. It swims around the tank but when it seems to rest, it sucks up to the intake and chills there motionless.
. It has me thinking, after my initial thought of dead, that maybe its just a wise fish and it has found a nice, secure place to sleep without having to worry about floating around into the other rainbow sharks corner (opposite side of tank). Is this normal? Do some fish sleep sucked up to the filter? Or is this a sign of something maybe not normal needing attention? Between this shark and the yoyo loaches that literally sleep on their sides, my tank has just became weird to me. Never know what is next, but always having a reason to think I have some dead fish.
