Update:
Added two powerheads
Added an Aquatic Life 115 skimmer
(both from the forum's members)
Last night around 3am, my wife woke me from my slumber and asked me to head to the tank. Unfortunately, one of the snails was ruthlessly destroyed/eaten by Matsuri last night (the punching noise was quite loud even though she was watching some late night TV she heard the entire thing). It might have been because we didn't feed it last night (we were feeding it every day and wanted to see if he can go a day without food, guess not...).
RIP White Shadow, the Turbo snail.
Circle of life.
