It's looking nice, but I would recommend you slow down. Two weeks is very fast to add 3+ fish, let alone one fish. Patience is very important in this hobby. I recommend you wait another month before adding anything else, and then add livestock slowly after that.
Yea slow down just a little.Helps in the long run. O and btw you may want to think about removing the bubble wands due to salt creep from them IMO. Cant wait for more pics...
