They are swimming through, there are tons of caves and places for them to get through.. If you look at it up close you can see how I stacked it. It's actually very open underneath the pile, like a hollow center. They were all at front in the picture because when i walk up to the glass they come flying out from the rocks :lol: they actually seem a lot happier in this setup than my other two above..JimA said:I voted for the 3rd one but, I think you have way to many rocks in there. While I am sure there are many a cave it just looks a piled up mess. No offense! Are the fish swimming through the pile or just hanging out front?
Still really liked the first one a bit.
A solution to this is to have a power head that you plug in during water changes and just move it around the tank with your hand to blow it all out from the rocks. Stir up the water real good and suck it out.fox said:#3 must be a PITA trying to get the detritus out. Could be a future nitrAte problem.
Same exact thing. When I pull the canopy the tank looks completely empty..GTZ said:#3. I have a similar setup with round, mostly oblong rock, not stacked quite as high.
It's great for the fish as they can swim about in the rocks like it's a maze. Easy retreats.
I have 25 fish in the tank and if they're sufficiently startled the tank looks empty, well except for the 3/4" yellow labs, nothing seems to phase them I expect yours are the same.
