Hi I currently have a 29 gallon fowlr tank. I think I have around 30 pounds of LR, possibly a little more. And then live sand as well, I'm not sure how many pounds. I have a protein skimmer, powerhead, and heater. Fish I have: 2 clownfish, 1 royal gramma CuC: 2 sexy shrimp, tiny hermit crab, and two fighting conch. I used to just have one conch, but he wasn't feeling so good and hasn't moved for weeks so I got another one to sift my sand for me. Problem is this second one doesn't move much either.... 1. Should I get another clean up crew member to sift my sand? if so, what can I get? 2. What other fish, if any, can I still fit in my tank 3. If I decide to turn it into a reef tank, about how much does lighting cost? And will I have room for more fish or should I stop at 3? 4. can i get more rocks? is it possible to have too much lol thanks!
