Hi Keen Angler,
Welcome to IA. I used to keep a planted tank as well some time back with all the CO2 injection system etc, if that is what you mean. I also had a Saltwater corral tank which was completely cycled and running for over 8 years till it got busted when I was on holiday and we had a power failure for 3 hours.
Did not keep fish for about 2 years after that, however just bought a Flowerhorn about 4 days ago. I was fascinated with that fish when I first saw it but never got one until now, I know the fish comes with a lot of ethical baggage but screw that
. Some of their versions remind me so much of Saltwater Angels like the queen angel.
