Hi guy just wanted to know what the best rocks are for a freshwater tank to make caves out of. If anybody could post pics of there caves would love to get some ideas for my bgk fish.
Slate seems to be one of the best. If its for the bgk you mentoned, try pvc pipe. I dont love just havin a big wite pipe in my tank, so i put aquarum safe silicone on the outside then rool in gravel or sand
