Hi riptide, thanks for the reply! Yeah I have one giant aptasia and about 5 or 6 tiny ones. I plan on getting a peppermint shrimp once the cycle is complete. I'm finding new critters all the time and in such a tiny tank!!! Only 3 lbs of live rock, I went crazy with the sand and have way to much.. But I'm going to leave it and see how it goes...maybe get a tiny jaw fish or somthig more suited for a nano that still utilizes the deep sand...?¿ any thoughts of nano fish that love deep sand ?? Sorry if that's a dumb question I'm pretty new at this only have had one 10 gallong tank in the past and I knew nothing then,only to change the water that's what kept it alive so long.. I know a lot more now but still am a total noob !! thanks everyone any help you can give is greatly appreciated!
