Quick Stock Question

[KrystaK]

I have an algae problem in Casper's 20 gal, I've been told that Otto's should keep it clear, and they're small. But it didnt occur to me until after I bought them that they may not get on well with Casper and his cory and Molly friends.
Does anyone have any experience with Otto's and Betta's or is this a new field? lol

I kept otos with my betta Ace (died a few days ago), and he didn't even look at them. Bottom feeders tend to compete though, so the one I'd watch is the cory.

It's only a single cory, I'm planning on getting him some buddies and moving him to my 30 gal tank after I move
Thanks

What about a nerite snail?
