I never got a decent answer for this...

is it ok to put baby cories in a 1/5 dived tank in my 55 gallon? will the tank be too tall for the baby cories?

If that doesnt work, i've been thinkin of putting dwarf puffers in the divided part

Have you tried posting in the catfish cradle? Maybe someone there would know. I only have short tanks and no baby cories so I can't help-sorry.

Cories live in much deeper water than 18", I think they'll be ok
