Hey all, I plan to make an actual fish stocking list and get opinions but wanted to ask this one up front. My ideal is to have a tomini tang, bristle tooth (havnt decided on witch one exactly) and a purple tang. I know aggression is key so when the tank gets built first off it’ll be a 60x24” tank. Plan to design the scape with three main island. Two islands on the left and right of the tank going I’d say 2/3-3/4 of the way up with tons of arches and swim through. Middle island will be more of a small cove for a higher light clam and easy sps but should also give a nice swim lane from one island to the other. My goal was to add all three at the same time and hopefully roughly the same size. What are the chances of success here? I’ve my lfs have all three of these in a 4’ Red Sea with not noticeable issues.
I can only speak from my personal experiences. I have found when dealing with Tangs and Angels, the key is to have a bunch and to add them at the same time. I would go with five and not just three. Keeping to the normal rules, such as different genus, makes it easier to keep multiple Tangs. Also, remember that most of aggression comes from the competition for food, specifically leafy algae. If you ensure there are always multiple algae clips with nori on them (wound up tight to allow for contrasting grazing), that will increase your success. If you don't have the ability to add all your Tangs at once, then you should start with the smallest and least aggressive and end with the largest and most aggressive.
I've kept a Hippo Tang, Purple Tang, Naso Tang, and Powder Blue Tang in the same six foot aquarium with ZERO issues amongst them. The Powder Blue and Purple Tangs didn't like any new additions (not just tangs) so I used the mirror trick on them with great success. The only reason I still don't have them is a marine velvet outbreak that wiped out everything in less than three days. I'm restocking and currently have a 1.5" Purple Tang in the display and a 4" Desjardini in the final three weeks of QT. I plan on adding a Blonde Naso, Yellow Belly Hippo, and Powder Blue to my quarantine tank in the next three weeks. To complete my Tang Gang. After the Tang Gang is complete, I will add a Regal Angel, Blueface Angel, and Female Japanese Swallowtail to go along with my 3" Majestic in the DT and 6" Asfur in QT with the Desjardini. Then I'll just need my Aussie Tusk, Falcula, Semilarvatis, Maroon clown, and Cuban Hog to complete the stocking plan. It should take me through the end of next year to complete my stocking plan because of my small QT tank but I can't wait for everyone to be in!
It might sound like a lot to some but it is a 300G with an oversized skimmer and oversized sulfur denitrator so water quality is and will be pristine (working on an algae scrubber for phosphates).
