@Steph72 hello. Thank you for replying. I have a pretty new system with juvenile fish. I have a 150g DT with 2 Vlamingii (will remove soon) 1 Pacific sailfin tang, a regal tang and 2 lawnmover blended (which are so graceful to watch) my lfs has a new stock, he has a couple of tangs that interests me such as Blonde naso, scopas and powder blues (which has a notorious reputation) however they’re all at least 2 inches larger in size than the ones I have. all these fishes come from the Indian Ocean hence a temperature of 27c is set throughout. I was wondering if I should buy larger fish and keep with juveniles which are well established?
