Oh so i got about 4 astrea snails and they have been doing a great job on my diaton(brown stuff, don't know how to spell it) on the lr
, but they don't even bother going in the sand unless they are moving from the wall of the tank to the lr
. Is this normal ?? i want something to help move substrate around. Any ideas ?? SOmething compatible with a yellow watchman which i am getting this weekend.
Also, is ok for the snails to be all over my heater and powerhead( they won't get sucked in because i have stuff to protect it)
