Definitely the first two work. The only issue maybe is the blenny and gramma may not get along but they probably will. The CJG is one of my favorite fish and should work great.In my tank I currently have:
2 black ice clownfish (captive bred)
I also have some fish in quarantine that will be joining the DT in the next few weeks, they are:
Neon Goby (captive bred)
Yashia Goby (captive bred)
Harptail Blenny (captive bred)
Foxface
I would like to add:
Royal Gramma Basslet (captive bred)
Court Jester Goby (captive bred)
Melanurus Wrasse
The display tank is a 40 gallon with a 29 gallon sump. I am about to separate my refugium out which will add another 15 gallons to the system. There are ample hiding spaces and caves in the rock. I will be soon setting up a protein skimmer, avast plank feeder, and am willing to add a reefmat if necessary. In addition I will be upgrading to a 125 about March of 2024. If the foxface grows too large before them, I will re-home him.
Do I have room to buy the extra 3 fish that I would like?
The melanarus may be a bit big for the tank. Probably won't cause any issues but they can sometimes be a bit aggressive. Overall there no big issues though and it will probably work.
Could I suggest some urchins and/or Mexican turbo snails though? They are great algae eaters.
