Hi! I’ve started a new marine tank which is an aqua one mini reef 90 (90L), and have added a wave maker. The tank is a couple months old and my plan is to finish setting up all of my corals first so I won’t get any fish for a while. I’m worried I’m looking at too many fish for the size. My ideal stocking would be; 1x Yellow clown goby, 1x Decora goby, 1x Red Hawkfish, 1x Blue sapphire damselfish, 1x tail spot blenny. Any advice on compatibility, between fish, with this setup or potential worries would be greatly appreciated :)

4th one to suggest no on the hawk. I also would say be cautious with the damsel. They can be very territorial and cause aggression issues for your other fish.

I agree I would say no for the hawkfish and for the damsel as well. I would try to keep it to 3, maybe 4 fish at most. My 40 gallon has 5 fish, so you are trying to fit the same amount of fish as I have but your tank is half the size.
