my problem is that if they are cave liking fish they'd probably have a problem with the two cichlids that keep all of the good hiding spots to themselves. They are kind of bullies leaving one cave to flush the fish out of another! I set up the tank with a lot of hiding spots to try and cut down on there territorialism*, but they just take up more space!
The rocks are pretty well rounded as they where removed straight from a fast flowing river, actually, just down stream from a class 4 rapid! but I'm still unsure about there size and ability to co-habitate with the cichlids!. Also does anybody know if they will help with the brown algae?
*Mispelled, sorry.
