I noticed my male's 2.5 gal gets dirty quickly; I then realized his blue mystery snail is the bioload culprit. This is a BIG snail. I have a smaller blue mystery in the 5 gal with my 2 girls, and the water is much more stable!
The big blue snail is going in the 29 gallon.
Long way to one question:
What is the bioload of a good-sized snail in compared to a betta or cory? We are all familiar with the "one inch of fish per gallon" rule; what's the snail equivalent?
That was my original post. I tossed M1 (Butch's snail) in the big tank. Over the next day or 2, I noticed that Butch was spending a lot of time under the filter outtake. This morning I pulled the top off the tank- he had, for the first time EVER, built a huge bubble nest!!!!
I guess he thought the snail might want to snack on baby bettas! I'm so proud of him! (Behind the filter outtake has absolutely no water movement. Clever fish!)
