they're good, i think this site even sells them, put some in your DT and some in your fuge if you have one. If not, create a place in the tank for them to reproduce and not get eaten...Like a small mound of LR rubble.
yes definitely could. search steve weast on google, you'll see his amazing tank, and then go the the incident or whatever. Its about a huge worm that was attacking his corals and inverts.
i have a ten set up at the front desk at my work, i'm using an aquaclear 70. I've got a 96w PC over it. Its an attractive lil display, and everything's healthy, but its very hard to keep clean.
Found a pic of the original 37...first ever attempt
Here's the 20 about a year ago
20 about 2 months ago, just before i took it down...
and the new 65g, almost 2 months old.(although the pic is about 2 weeks old)
yeah i bet they will, i had one live pretty healthy under PC's for a couple years and put mh on the tank and it developed the bubbles in like 2 months.
