CAlvin,
Yeah, I've wondered about that too.....I wanted as much rock as possible for the filtration, plus I wanted plenty of hiding places for the 2 eels.....kind of a trade-off I realize.....on the right pile the shark can swim all the way around it....when I was stacking that side, I made sure to leave a gap at sand level....I didn't start stacking rocks against the back wall until about 6" off the sand level, so he should be able to swim back there too.....not so on the left side.....I stacked it first and didn't think about doing it that way until it was already done.....thanks for the tip about thepetshop.....I've found 3 sites so far that sell Catsharks....they are kind of hard to find.
For those of you with these smaller sharks, do they ever move during the day? I'm just trying to get a feel for their activity level.
