Hello, all! I am new to the site, and new to garters. I am going to be getting two baby neon red-sideds (sooo excited!!), and was thinking of raising them together in a 20 gallon that I already have. I am wondering if this is acceptable, or if it may be a bit too big for the little guys..
I am going to be buying another tank for the snake currently residing in the 20-gallon, so thought it would be convenient to house them in the 20-gallon (after santizing, of course) until they are adults, then transfer them to a 40-gallon.

Thanks!
