MUNLIT Stackable Aquarium Decoration Rock Caves, Fish Tank Accessories Cave Hideout, Hideaway for Shrimp Cichlid Cave Hiding Breeding Spawning, Betta Fish Hideout (Alien Style(Medium))

I bought this because I needed a hideout for my beta that had large openings so he would stop shredding his fins, he’s a big boy. So far he really likes it. Comes with a few rough spots but they give you a little emery board to sand it to your liking. Looks very nice in our tank.

Our Beta fish took right to it.

Arrived in pieces.

My betta loves spending time in his cave. (he has a broken swim bladder and can’t dive down very easily. When he does dive down he loves wedging himself in the cave to stay down) From the human perspective it’s hard to clean and often is still brown when I’m done. It’s for the fish though not me!

Comes with file to further ensure smoothness required for Betta fish, as they have sensitive fins. The outside is smooth and inside smooth enough, but I filed entrances and inside more.
