Re: RSM 250 Max Newbie
Hey Iain, I've heard mixed opinions on number / types of snails. Some people suggest a lot of them (like 60), some very few (like 20 total in your tank)... 20-30 is probably about right - otherwise they may starve. The one thing about turbos - they get huge and knock things over. 10 turbos would also equate to a lot more of the smaller snails, so that might be overdoing it with turbos IMO... I only have a couple in my tank and a number of others. I'd advocate for getting different types of snails - just so you have a nice variety and also because some will be better at eating certain types of algae than others. Cerith, Nerite, Astraea, and Trochus are all great. Plus Nassarius for churning the sand bed and eating detritus and leftover fish food. I haven't lost a Cerith or Nerite snail yet. Astraea can't right themselves when they fall over, so you may lose some of them, but to my surprise I think I've only lost one of them so far. Trochus are similar to Astraea, but they can right themselves if they fall upside down. Surprisingly though, I've lost a few Trochus snails in my tank. One died on its own (I think) and was dinner for a Nassarius. Another was being eaten by a scarlet reef hermit (first time I had a problem with one - maybe not enough food in the tank). I'd suggest avoiding Margarita snails though. The temps in our reef tanks are too hot for them and they usually won't survive. BTW, I'm no expert here, but I read a lot about them before making my choices. Just passing on that info. Take care,
