okay 2 of my 3 temensis are acting funny now....seems like they are getting what my mono got...breathing heavily,sometimes going to the top of the tank like gasping for air then sinking to the bottom just hovering there,not eating,.. and one of them has redening on the outside of the gill..not sure if another fish caused that...also the temensis that is acing normal has been chasing the other two around ramming them so i dont know if he ruptured something...the tem that was punking the others is doing fine and still eating vigorously ( and chasing the other two). I did a water change, added salt, and raised the temp to 86....what else could i do??
Seems to be enough air....on one end is a powerhead and in the middle is the outflow of the canister filter....only place there is a small amount of bubbles is on the right side where the intake for the cansiter is....i could add an HOB filter....
oh duh...yea water, the outflow from the canister filter and thats about it...i raised it so that it splashes and creates air bubbles....thats about it...
I think they are blind...i have no idea how that would happen...they keep swimming around bumping into things then once they hit something they turn around and swim the other way til they hit something else...this happened to one of my monos....what could it be???!!!
I would add more air. It's strange that the one is still fine but when this happens usually the water doesn;t have enough o2 in it and you need more surface agitation.. so make sure your water level is low enough that your filter is making agitation.
