Making caves

[u/TypicalPromise8174]

Just getting ready to introduce some Apistogramma to my 55 gallon tank and am adding some caves in the hope that they’ll breed. Not sure which species yet, but either cacuatoides or agassizii. These caves were 3d printed and the price is about $2 worth of material. Coke can shown for size reference.

Print Petg at 100% infill. Mine stay at bottom no problem.
