Is it possible...?
I've posted here before that my clean up crew died off in quick fashion, save for one lonely snail that still lives. About 11 snails died off in my tank and my thought was that the hermits had killed them (I would see them playing with the shells each morning)
I have a 20-gallon, just started the tank in February, it is covered with a bed of 2" of live sand and about 12 lbs of live rock. I also have a filter running, and I turn on the lights for about 10 hours per day (just because I work from home and I like to watch my tank) with a goby, firefish, and clown fish all co-exiting happily. Is it possible that the snails died due to lack of food (algae) in the tank? My one snail seems healthy but I have very little to no algae or molds growing in my tank. There is a very fine layer on the back and side glass. Should I have waited to introduce the clean up crew? How long does ti take to build up a healthy layer of good algaue that will cover the back of my tank?
...No seriously, I don't know what I'm doing.
