I am glad you asked this, because I was not clear. You can not keep both the C. loricula and C. argi in a 26 gallon tank. They would not get along together. You can pick one of these two, and then add 1 or 2 more small fish.since my tank seem to be maturing in the proper way.. now im thinking more in to stocking the tank...
lets say i get this two fish C. loricula and C. argi.. are those the only two i can get?
or can i add any of these as well??
If you choose a Yellow Tail Damsel (no other Damsels) or a Pseudochromis, then you will probably be best sticking to just 2 total fish.
If you skip these, and go for smaller peaceful fish, such as Basslets, Blennies, Gobies, and Jawfish, then you can probably have 3 total fish.
I think your best overall choice would be to start with a small Blenny, then add a Royal Gramma. Then allow the tank to mature for about 3 to 4 months, then add a Flame Angel.
By the way, hermit crabs do not eat aptasia. I would suggest you add 3 Peppermint Shrimp, which do eat aptasia. Do so as soon as your ammonia and nitrites are zero. You want to add 3 because not all Peppermint Shrimp eat aptasia, and adding 3 increases your chance that the correct species was purchased. You can not tell the different species of Peppermint apart visibly. The distinguishing marks are almost identical. These Peppermint Shrimp will be compatible with the other livestock.
