What types of fish would i be able to put in there? Any shrimp crabs and coral.
types of fish depend on what type of tank, reef, fish only passive or fish only agressive, so basicly what other fish/inverts you want to keep. (ie if you want a trigger then no hermits/snails) there are lots of combinations youll have to figure out by reading the articles on here and other sites. read, read, read...
shrimp/crabs/corals also depend on the animals pourpous (some eat certain types eat algae, some clean sand, some clean fish etc), light, water conditions/temps, and compatbility with fish/inverts.
compatability is one thing you can research while your tank is cycling. but you should figure out what fish/corals you want and how much live rock to buy. your lighting is going to dictate the corals you can keep.
