my golden dwarf was great made a nice addition and was the only tankmate in my 20 gallon reef had him for a while then sold the setup for financial reason's
he's still chilling out in my 10 gallon QT until i can get my 29 biocube cleared out (2 mean azz damsels i don't want in there with him)
right now it's got like 8 pounds of really... not quite porous, but it has a lot of larger sized holes in it... tahiti LR and just a little LS for cover, filtered with a fluval 4 internal filter and a 24" hagen GLO T5, got some zoos in there untill it comes time for another quarantine
the cube has like 30# LR and 2-3" LS plus some of the biggest shrooms i've ever personally seen
