i have a 30 gallon tank and right now i have peaceful and semi-aggressive fish in it and i wanted to get aggressive but now i want to get saltwater but im not sure which one ill have to do less work on and which one cost less but ive done some research on which fish are compatible and all the fish i wanted were compatible but theres to many i think i want 2 bicolor blennies 1 coral beauty angle 2 damsel yellow tail 2 blue sapphire damsels 2 ocellaris clown fish green mandarin 1 banded coral shrimp and 1 bicolor angle fish so i was wondering if i would be able to have this many fish if not tell me which ones would be easier to take care of and which ones are more to be compatible with each other and what coral i should get and live rock i should get well not really what live rock but if i need a protein skimmer or if i should just go with freshwater aggressive fish please help me i cant choose
