Still setting up my 75 Gallon (48x18x20) tank and in the planning stage for the fish...
For the tangs, I have a local guy that will gladly pay for and switch out when they get too big with smaller ones, the bristletooth, should be good to keep (i think)
I figured they would be added in this order over the next year.
2 Gladiator clowns
1 Diamond Goby
1 Bangai Cardinal
1 PJ Cardinal
1 Dotty Back
1 Flame Angel
1 Bristletooth Tang
1 Blue Tang
1 Yellow Tang
1 Six Line Wrasse
is this the correct order to add?
any issues with all these fish getting along with each other?
I don't have a lot of experience yet, but my research gives me a few concerns with your stocking:
Dottybacks are known for being jerks often, though some are peaceful. If you like the look of that bicolor dottyback, you might consider a royal gramma (
Gramma loreto) instead which is much more likely to be peaceful.
Sixline wrasses are also known for aggression, but some are peaceful. You will probably have a better chance of less aggression in a 75-gallon tank as opposed to smaller tanks. If you like the sixline, give it a try, but keep in mind also that, if you see aggression and try to remove the sixline, these are usually difficult fish to catch from what I have read.
In agreement with
@blaxsun, I would not try 3 tangs in a 75-gallon tank based on my research. You might succeed better with only the bristletooth and 1 other (you might succeed with all 3, possibly, but there are much higher aggression risks, especially in a 75-gallon). I personally do not like the idea of rehoming fish because they grow too large for current tank and will probably never do it, but it is a valid consideration if you have a solid plan with someone that has agreed to rehome them. Aggression could cause this to become necessity much sooner.
Flame angels, though quite beautiful and interesting, are known for difficulties in keeping them alive, especially in smaller and/or newer tanks. The tank should ideally be well-established, probably a year or longer, before introduction. A 75-gallon may work for enough size, but I can't answer this for sure due to lack of experience or information from those with experience...
Overall, this looks like a reasonable but slightly risky list for a 75-gallon, and I would categorize this list as heavy but manageable bioload for this tank size based on my research.
