I've had a 2.5 gallon saltwater tank set up for two weeks now, my ammonia, nitrite and nitrate levels seem solid, and my salt gravity is between 1.025 and 1.026. The little critters that came with my live rock appear to be multiplying, the heater keeps the tank at 75 degrees, I have a small betta filter meant for a 6 gallon that provides a fair amount of water movement, and the filter cartridges it takes contains filter floss, activated carbon, and ammonia removers. the "dead" base rock i bought is starting to turn the same color as my live rock, is there anything else i should look for before i add fish? the lady at the lfs recommended a striped blenny and maybe a hermit crab. At some point I would like to add corals.
