Hi all..after having nothing but hermits and snails for weeks, went to great store and was told because we had bad worms, 1st fish should be sixline wrasse.Now I see that they should be added last?? Planning on docile community tank, 75 gallon with lots of rock caves.He or she is doing great, should I hurry and add my 2 clowns or is it ok to wait??Thanx
