Hello, my tank had been running about 6 weeks with 2 small clownfish and small CUC hermits/snails. I want to add Tomini Tang. I don’t have algae outbreak due to snails and hermits, I know that I will have to supplement food for Tomini. Just want to make sure tank is stable enough for Tomini, water parameters are within normal limits, monitoring Nitrates at 10-20 ppm per API test, doing 20% water changes biweekly. Also tank is standard 75 gallon 48 inch long.
