Dan,
Interesting aquascaping in your 90g
What species of SH are you going to get for your 25g? Just wanted to let you know that SHs need 3 times their body height for their mating rituals. Also, if you haven't already thought about it, maybe put more rock in the tank. More rock will give pods places to thrive which will give the SHs a bit of natural hunting to do between meals at the feeding station. HTH
