7 gallon advice

[teddah]

I'm starting a new 7 gallon tank and am looking for some advice. Eventually, I want to keep 3 various Clown Gobys. I found about 12 pounds of live rock, but don't know what else to put in. What corals/plants do these fish like? Do I also need live sand? What about snails and hermit crabs? Do I NEED them? Also, if the live rock isn't already cured, what is the best way to do that? Thanks ahead of time!

you will want live sand i bought some in the classifieds cheap
to cure the rock i would just put it in the tank with no living creatures so it can cure
i dont know if 3 clown gobys will work or not
snails and hermit crabs are good i would only get 2 hermits and a snail

the clown gobies will kill eachother they need to have a large tank to beable to live toghether and in a 7 gallon tank you could only keep one fish :thinking:
