Marina Polyresin Cave Aquarium Décor, Small

I would not use this for a male betta unless I was willing and able to do some sanding, as, like most aquarium decor, the insides have some pretty jagged spots. However, for shorter-finned lady bettas and most other small fish, this is a great cave. It's generously sized; the opening is actually big enough for my Bolivian ram (a dwarf cichlid). It passes for natural rock from the outside, though glo lights will pick up some of the painted texture. It's a great size for a 5- or 10-gallon tank. The bit of fake plant came off on mine before it even got wet for the first time, but that's okay by me, since I wasn't sure I liked it anyway. Especially at the sale price I paid, I would definite I would not use this for a male betta unless I was willing and able to do some sanding, as, like most aquarium decor, the insides have some pretty jagged spots.

I just bought my first betta fish and he loves it. It gives him the privacy all Betta’s need. It is slightly on the larger side. I have a 3 gallon tank and it takes up a little more than half of the room on the ground but still provides ample space for him to swim above. It’s a great decoration for bettas. He loves it!!

It arrived entirely broken into 8+ pieces. Other than that though, it's actually a moderately nice decoration. Its pretty large for the price and the edges on the inside aren't sharp. I planned on using this for an extra hideout for some shell dwelling cichlids. Looking at it, Ican tell it would've been a perfect addition to their tank, had it not been broken

This little cave is actually bigger than I expected it to be. Not sure if I just got one from a good batch but there are no rough edges that snag on my betta's fins and he likes the privacy it gives him.

I bought this for my 1.5 gallon beta tank, and it won't fit in! It's way bigger than I thought. I had to put it in my big fish tank, but my danios love it! It has beautiful color and detail.

This cave looks great in real life. The colors are bright, it looks natural, and it's very large. And probably is great, however it arrived completely shattered. Guess it's my fault for ordering 40 lbs of gravel in the same box as this...

We thought this would work in our crabitat, alas it was waaay to big. The initial one delivered was broken, so we couldn't really judge the size, however this is now sitting vacant in our basement :( Too bad, b/c it's really cute. Waaay too big for our little fiddler crabs.

The cave is bigger than I thought but it's really nice and my betta loves it. I did have to remove the leaves because they were pretty rough and sharp but over all Its nice and goes with pretty much everything in the tank.

I bought 2 of these. They are very nice. Good price.

Works out well for all of my fish. The exterior is smooth enough not to damage my betta and the other fish seem to enjoy it as well. The plants on the side were a little rough and had to be cut, but everything else about it is great.
