Hey guys i just added 3 hermits, 5 snails and 3 damsels to my tanks and they seem to be happy. I dont have my live sand substrate down yet because i bought the fish and didnt wanna cloundthe tank and didnt wanna keep them in the bag for way to long my saltwaterfish store is almost an hour away, what should i do when adding substrate i have and very light bottem of crushed coral right now can i lay live sand on top of bad idea also with the fish and inverts can they handle the cloudyness or what? also how long until i can start adding keepers?
