Hi! I got my first mystery snails last Wednesday (thanks dixienut!) And just wanted to make sure I'm doing everything I should be for them. I have a 17 gallon hexagon tank, there's probably only 15 gallons in there cause I have the water level lowered a little bit for them. I have live plants but there not doing so good, a few are dying slowly... The substrate is half crushed coral and half aquarium soil. I've had the snails since last Wednesday and 3 of them were really active the first 2 days, one only moves around in the dead of night. Friday and yesterday they haven't been very active. They ate some cucumber and an algae tablet the first 2 days but haven't showed any real appetite since then.. I'm OK with this non activity as long as its normal. Thanks, Jess!
