Hey I'm Ethan. I currently am coming from a hobby of tropical freshwater tanks and started a new go at a Reef tank. Originally I started with a 5.5 gallon nano set up, live sand, live rock, a few hermit crabs and a blue damsel. I had this tank for about 2 months when I decided it was time to upgrade to my 29 gallon. So I've been running this tank for about two weeks. I added bio spira right away while ive been monitoring the levels and everything seems stable. I recently just added 11 hermit crabs as well as 3 turbo snails. I have live sand and live rock from my old tank that has been cycling for the two weeks, as well as some new dry rock that I added since I needed much more. The levels all seem good I have lots of testing equipment and everyone seems happy. The damsel I took back to the LFS because it was straight up cold blooded and aggressive. As with anything fish related, especially salt water I know not to rush and to be cautious about everything. Now on to my question, when should I consider adding fish and what kinds do you recommend? It's 29 gallons, with LED over head lights. I think my first sign is going to be that purple algae, but also just steady parameters. I also plan on sharing pictures soon.
