Welcome to the fun!
Sounds like an exciting mix of activity you have going on!!! When you post some tank threads, post the links here, that way we can see and follow along. I would like to see them! We don't get too many brackish tanks posting. I have a few Red Mangroves in a container, I was considering which direction to take them, and would especially like to hear what you have going with brackish.
New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?
