They did, and I removed some water. The sand all fell in in one chunk and splashed the wall.
Iffy, as apistogramma are bottom dwellers and they spawn on or near substrate, easy access for BN pleco to eat the eggs, but if the tank is large enough then you may be just fine, provide extra caves though.Would a bristlenose pleco get along with apistogramma? I keep seeing them in stores and they’re growing on me, and I’m sure it would love this big chunk of driftwood.
