Wondering if anyone had any recommendations on how to build caves. I thought it sounded simple but I am unsatisfied with my "cave building". I Decided to take a concrete block, break it into pieces and try to add on to a store bought cave I already had. I didn't quite go as planned. I like the look of the concrete block but I "think" i need to go with smaller pieces of block. Im not 100% concerned with how it looks because I do plan on putting plants in the tank ( after lighting) but I do want something that will be sufficent for my two cichlids that won't cave in on then and crush them and will be enough for them to run to cover. Please tell me what you think, should I go with smaller blocks, get rid of the cave,get new material ect...
