There is no percentage of protein to prevent bloat in Tropheus. Vegetable protein is different to animal protein. Saying that good water and good numbers and good maintenance and you can feed em any flake and sometimes get away with it esp with juveniles brought up on it. If you want to get bloat chances to a min then feed em a food with only veg proteins but the lots of folk use pellets like NLS (inc myself to try and get more breeding from adults) and get away with that. To be honest other than a protein level that is quite low but not given how much is veg protein and how much animal its pretty hard to judge if this is a good Tropheus food or not.
Ingredients that seem odd to me for Tropheus are oatmeal, soybean flour, and the shear amount of dried spirulina algae. Still I have seen far worse used with great success.
4 Ikola is not a stable mix. Niether is adding 10 new guys to the 4. I would for sure swap your four and pay for a bigger group rather than adding to em. Adding Tropheus to an established group no matter how rediculously small is usually less good than changing for a bigger group of Tropheus that already get on.
This should be your main concern not the food!

All the best James
