I am looking at stocking my 42 gallon tank. I don't know what to get. First of all, I put a rocky substrate instead of sandy (bad move). Will gobies, jawfish, or blennys do well in a rocky substrate? Next, it is small so I don't know what fish I can put in. I would like some wrasses, but hear they jump a lot. My other option is some more rare damsels that I have found. Will they attack the low lying fish like gobies, jawfish, etc?
Thanks!
