Hi all, was looking for some different suggestions of fish and unique invertebrates to add to my research list/cart. Right now my tank is a very stable 8 months old and I just haven't had the extra money to shell out to get fish because of unfortunate personal events but I'm finally able to afford fish now my tank just has snails around 15lbs of live rock and a 3-4inch deep sand bed, I'd prefer to stay in the 10-75 dollar range per fish and would love see if anyone has any unique invertebrate ideas. Thanks all such much for your time!
