Well its been a week since i added 10 hermits to my newly set up tank they are the only things in there right now besides one snail. and today i checked the ammonia and it is going down now was at 1.0 for a while and today it is at .50. So i was wondering should i add about 20 more hermits tot he tank now? there is a decent amount of dead stuff because i used dead base rock that was once alive so there is still some things on it. BTW the tank is a 55g tank that has been set upf ro 2-3 weeks
