Cave building???

[johnny leftist]

I guess that'd work in an unoccupied tank but if I had fish in there i'd be too scared of them getting stuck. That or the water current ruining all that hard work

Yeah I'll probably use it for smaller caves to keep them together but for big caves its just too heavy to try and do that

What size fish are in the tank? If they're not big like oscars or plecos you can often just stack the rocks and let gravity do the work.

I have an 8 inch cat fish and then I'm going to get a small clown knife that like 3-4 inches I've had them before so don't criticize me on what I getting please thank you
