Gee, pond snails... where have we heard this before?
Anyways, my 10g betta tank got a few hitch-hiker pond snails when I bought some live plants about four months ago. I researched them right away, and knew they'd become a nuisance so I removed them. The problem is I didn't have the heart to remove them permanently.
They have their own 2.5g tank in which they obviously frolic freely if you know what I mean. Plus, I can't find all the egg sacs in the 10g so unless I take it apart completely and scrub, scrub, scrub (it's cycled, so a pain to do, and then re-cycle the tank), I'll keep finding pond snails in there.
So, about 50 pond snails and dozens of egg sacs later, we're at the point that they started to make egg sacs on each other. Quite a sight.
So what to do?
a) do what I'm doing now (they have a 2.5g tank, fed algae wafers, 100% water change once a week)
b) add an assassin snail
(there's enough food supply for one, plus the weekly additions from the 10g)
c) other (whatever you guys suggest, but I don't think anyone would buy them considering their reputation)
Also, I have one ramshorn snail, which I've grown fond of. His name is French Fry, and he lives in the 2.5g. You can kind of see him on the bottom left in the photo. I really like him so I was thinking about moving him back to the betta tank. Good/bad idea?
Most of those bigger specs that make the tank look dirty are actually egg sacs, especially in the upper corners.
