I have decided to alter my stocklist to allow for the mandarin, without the CBB as a source of competition.
My still tentative stocklist for my 72''x18''X22'' or 125g with 40 gal sump(looking at going larger on the sump, but at least 40 gallons)
is:
1 false percula clown
3 leopard wrasses (meleagris)
2 banggaii cardinals
1 African Flameback angel
1 green mandarin
1 tailspot blenny
1 red striped, peppermint, or candycane hog
5 blue eyed cardinals
3 red or purple fire fish
By numbers it is a bit overstocked by some standards, but with good skimmer, moderate feeding habits, an adequate CUC, a remote DSB and chaeto for nutrient export, and given the fish are all smaller and have low bioload, I think this list should be fine.
I have composed and scrapped at least 2 dozen stock list and after seeing a 125 in person, I realize the height, to my eyes would have larger fish, like swallowtail angels, Copperbanded butterflys, and tangs, looking out of place. I also think that the shallow depth negates the need for surface schoolers, like flasher wrasses or anthia, though they are still suitable and I could have chosen them. I just set out to occupy all levels of the tank with compatable fish, that filled the niches of hoverers, rock dwellers, lurkers, and bottom dwellers, and reef schoolers. I tried to aim for fish that all ate the same food or could graze much of their diet from the live rock, to keep the bioload low. I also like to include banggaiis and glassy cardinals to tone down the look of lots of colorful fish, so that the overall look is not one of hand selected fish and more that of a natural reef scene. Since I am getting my tank next weekend and won't be adding fish for several months, I might still tweak the list. I will be adding one fish type monthly and monitoring the water quality. If I reach a stocking level that compromises the water quality, before I have all of the fish in the tank, I will rethink things then. I am satisfied with this list for now and think it makes for a peaceful and pleasing mix of fish for a mixed reef. I am also considering a taller tank, maybe a 135, so with a larger tank or sump, I am also closer to being at a more traditional stocking level, though I consider this one high, but not gangerously high, with proper maintanence. Let me know what you think.
