Good for plecos not for mixed tank
I have a tank with 2 goldfish one fancy and the other a black Moor. I got this for my new brittlnose pleco. This was in the tank for around 3 days until today where I noticed my black Moor was missing. Checked the cave and my black Moor was stuck in it, not sure how long but they're now missing scales and badly injured and lethargic. I hope they manage to heal from this but just saying, don't buy if your plecos live with other fish that may get stuck.
Best cave I ever had!
