I've read where you can keep them with groups, and I've read on here where it says don't mix basslets, but it always seems to depend on the individual tank and fish...By this weekend, I will have about 220 lbs of LR and the RG is a new addition to the tank too, it's only been in the tank a few days, so I'm hoping he should be fine when I introduce the blackcap...There are plenty of hiding spots in the tank...If it doesn't go well, I will take him back to the LFS, but I'm hoping it will work out...
