2 spots should be fine with the blenny since they will not occupy the same space/level of the tank. Note that 2 spots are not one of the easier fish to keep alive long term.
So after doing some research today I realized that the list I put together last night wasn't that great. What with Dottybacks killing shrimp, and Anthias being recommended a larger tank. I think I've come up with a more suitable stocking list, it seems like I have a lot of fish but with the majority only being around the 3" mark is it actually overstocked?
1x Kole Tang 7
3x Black Bar Chromis 8 (Most likely will only be 1 left when all is said and done)
2x Clownfish 6
1x Firefish 1
1x Tailspot Blenny (I think the Blenny/Goby combo is alright as far as aggression goes?)3
1x Twospot Goby (Read above) 5 (later addition as the sandbed needs some life so it can feed. may want to wait even longer.)
1x Carpenter Flasher Wrasse 2
1x Royal Gramma (Not sure if he will be too aggressive or not?) 4
Then for inverts
1/2x Scarlett Cleaner Shrimp
3x Peppermint Shrimp
1x Green Emerald Crab
1/?x Clams (I'm thinking Maxima, but as this is my first Clam I'm not sure what would be best?) Maxima would be fine.
Whats left of my Nassarius/Trochus/Cerith snail population
What order would be suggested for adding the fish in? I was thinking the Kole Tang and Royal Gramma would be the last two in hopes that the more peaceful fish can get their territories established beforehand. Lastly, sorry for jumping around so much, but I think I'm finally happy with my choices of fish/inverts.
