As of today, I've probably lost about half of the batch. It's hard to say because there are so many snails in that tank that corpses disappear before I get a chance to see them.
Some look like they're improving. Heading to Petsmart today to see what they've got on their meds rack.
On another dull note - Lost my male EB ram. He spontaneously bloated up and died. Female looks great, male looks dead. Also really strange for fish that have been spawning every month since they generally don't do that if they're not healthy. Grrrr. I don't even use the same WC equipment on my tanks anymore and the two tanks get filled with different water, so it can't be related, but it's still freakin' annoying.
