JC,
Welcome! It is nice to see and feel your passion and excitement! Must be a rush to be back in the hobby with not 1 but 2 tanks! Pretty cool!!
It sounds like you are off to an awesome start and have things churning along nicely and doing what works for you!
Any pictures or video to share?
I agree with bumping the numbers up a bit, sounds like you have things in order so you can support a few more. It will fill the tanks out nicely and the fish will like more mates. Seeing any issues with that mix of the 6 inch boys vs the 3.5? Thats a big diff in size...
Always caution qt and all... if things are rolling now, may want to leave well enough alone! Call is yours! Best of luck, look forward to seeing more!
