alright.... i'm getting a new 29 gallon tank for and angel, platys, mollies, and cory cats. so, i was thinking of maybe going with stacked rocks and light planting with low light plants. BUT i can't seem to find anywhere that sells the kind of rocks i'm looking for. there is an old abandoned quarry (the people started digging and then they hit a natural spring... now its a large pond) that i think has granite in it. could i find some small rocks i there? anybody have any other neat aquacaping ideas that my angel might like? i have attached a rough plan, but its not exactly what im looking for. more natural shapes, not squared like in the plan, but thats trouble on paint. i have a better hand drawing that im going to try to scan in. i really have no experience with plants so i was going to use the rocks as a natural centerpiece and a way to add some privacy with just a few easy plants to start. any other ideas/suggestions? i was also going to try to make the rock stack sorta thin so there is space behind it for my angel to swim around in. also, can concrete (like concrete edging stones) be used in aquariums? oh! also... substrate will be pool filter sand (i think). here is the new scan!
