Hear me out So I’ve had my ten gallon reef tank setup for around 3 months and my mother bought a baby blue tang from the LFS because she wanted a dory. I don’t know much about blue tangs since I only had a pair of juvenile clownfish for less than a month but when I searhed it up it says they require a bigger tank. Right now she has plenty of hiding places and she eats quite well and likes to remain close to the circulation pump. I make sure all of my water parameters are at zero and ph at 8.2 every three days and I’m running a uv sterilizer and surface skimmer as well as over filtering the tank. Water is crystal clear and it has no signs of sickness. I want to know if I can keep the tang in the ten gallon tank for now with full intentions of putting her in a 90 gallon tank once she gains another inch or two on her and then upgrading to a bigger tank once she gets to around six inches. I will move her to a bigger tank I just need to save up to buy more live rock and live sand I have the tank already since I used to own discus two years ago until I moved back to Georgia. Sold the fish but kept the tank. I did try to return it but they had a 24 hour return policy and I went two days after. She has grown on me and I have fallen in love with it.
