Apistogramma Breeding Cave (Improved!)

A cave for apistogramma breeding or any other small aquarium fish that uses crevices or caves for spawn.

Improved! Added extra basement space with a hole to push in gravel or sand (or even a weight of your own) to hold down the cave better as some people say they have had issues. Added a more tubular model as well for variation.

Includes 1" hole that is big enough for most apistogramma females to enter and lay eggs. Most males will not be able to enter, and will instead release their milt at the entrance and fan it into the cave with their caudal fin (as they do in nature). Depending on your printer, you may want to add supports for the center dome. I was able to print using PLA on a P1S with a 0.4mm nozzle with no supports (I did use needle-nose pliers to pull out excess strands).

You may use any aquarium-safe filaments such as Food-safe PLA (may absorb water over time), non-additive PETG (probably the best option), and undyed/additive-free ABS. Don't use hydrophilic plastics like Nylon or plastics that leak like Resin. You may also want to cover in a foodsafe coating.
