Tank Dilema

[zippy19]

I have 2 ACF in a 5 gal. A 10 gal. with 5 Neons, 3 Guppys, a shrimp, and a little red crab. Setting up the 20 gal long now. I was planning to move the frogs to the 20, they’re 4” long now when extended. Wondering if this the most economical use of tankdome. I’d like to breed the guppies. Should I move the fish to the 20 gal. and the frogs to the 10? I read that the 20 gal has more surface area for oxygen transfer, and the that frogs don’t care for highly oxygenated water. Any opinions?

Also how big will the crab get, and will it bother the fish?

depending on what sort of crab it is, it will need access to land aswel as water. they catch and eat small fish like guppies.

i'd move the crab for the time being into the 20 on its own until you know what sort it is.
