Yes, it's a 2FT tank.
The firefish has been inside for 2 weeks plus, it don't really like to jump. I guess unless really sudden movement will make it jump.
I'm using T5 HO. 4 tubes but 1 blue burnt.
"Tunze" > you mean the powerhead or the return pipe? or both?
Skimmer not on, as I was feeding the coco worm with some plankton and need to turn it off for a while.
Maxstar81, Thanks for your advise!
By the way, what do you mean by bleached?
