Ok so here is the situation: I've got three nano tanks setup and I just added red ramshorns to all three however in one tank they are happily eating and moving around while in the other two they seem to be struggling (not moving around staying in shell etc. for more then a couple days).
Tank One (happy snails)
Temp: 68 degrees (room temp)
Substrate: larger black decorative dollar store rocks
Friends: river snails
Tank Two (sad snails)
Filter: red sea nano
Temp: 78 degrees
Substrate: Zoomed black reptisand (black quartz) over MTS
Friends: betta (very happy)
Tank Three (sad snails)
Filter: small air powered
Temp: 70ish degrees
Substrate: Zoomed black reptisand (black quartz)
As you can see the only connection I can make is the reptisand, could it be too fine grained? When I pick them up they have lots of sand stuck to their "door". Its supposedly inert quartz. When I moved most of them to the happy snail tank they all perked up.
Tanks aren't medicated, water parameters are all in the norm and share same aged tap water.
Sorry for long post, thanks for help.:frown:
