Redoing a 65G tank
After a year of having a planted 65G tank with a community, I'm thinking of redoing the design and do more hard escaping (rocks). Naturally talking to the experts and getting their opinion is always good for a major project like this, specially since I've never done it before. So here are my thoughts and what I'm thinking to do. Any comments or advice is greatly appreciated.
1) The end goal is to have a community of, sword-tails, clown loaches, zebra danios, 1 angel, and a few bottom feeders.
2) I'm planning to change my mixed gravel to black and white sand (2 color) but not mixed. Any issues on sand? I've heard sand is better for plants and easier for bottom-feeding fish, but it's harder to keep it clean and vacuum.
3) As part of hard escaping, I'm planning to stack some layered red rocks, but this maybe be unstable. Are there any tips or tools (e.g. gluing) to make sure they stay stacked and stable?
4) I'm using red rocks that have the layered look on them and are very soft. Any ideas if they are ok for aquarium usage?
Any other advice to help me on completing this project ...?
