I don't have a 20 long but I do have a 20 tall sitting here.I'm going to suggest a 20L. It'll be easier for her to reach the sandbed.
Going to have to break down and buy a light for that tank too.
AND my pederson shrimp is missing!!
So sad, maybe too many things went in at once I think?
If I don't find him I will buy another for this second tank and he'll be in with the longfin.
Past two days have been HECTIC!! I just wanna relax.
