Isn't that aggravating? I know these guys know their fish because their store is astounding, the stock incredible and healthy. So it comes down to the whole give-us-your-money thing. What a shame.
So...skirts could move out, to the 29. My only concern is the nosy loaches, but since rams aren't cave-dwellers, perhaps it could work.
You just opened up a whole new realm of possibilities!
I have 3 fairly good sized loaches in the 220g and they are either the dumbest or smartest fish in there. They "know" when pairs are getting ready to spawn and pester the pee out of the pair no matter how many times they get their rears nipped. They have managed to eat a few freshly laid clutches but the rams and angels are learning to spawn in more protected or protectible places. What kind of loaches do you have?
