Hey all, so I want to divide my 56g (2'x15"x18") and was thinking of perhaps stacking rocks up rather than shoving a plastic/glass/etc divider in. I basically want to divide up cichlids and was thinking of taking approximately 20cm x 20cm x 20cm lava rocks on top of each other plus smaller stones in between to fill the gaps. My questions is, might the tank break? I know. Tanks can hold a lot of weight, but this is concentrated weight in a line across the tank we're talking about.
What do you guys reckon?
