Went to a fantastic aquarium a couple of days ago. So clean, no sick or dying/dead fish, just oodles of healthy, happy fish. The owner is a fish fanatic who left me for dead with his knowledge. I discussed setting up a reef tank with him and he reckons I'd have few problems and that he'd help me choose the right fish and start from scratch.

You know what has amazed me more than anything though? My fish at home are healthier and happier without me running round after them. That's exactly what happened with my parrots years ago. I used to run round keeping everything as perfect as I could and then when I started the dairy they got a bit neglected but they all thrived and only died of old age after that.

My theory - I'm overcleaning the tanks and not letting the good bacteria get a good chance to do their thing AND maybe overfeeding. I'm going to try staying at the 2nd weekly water changes for a bit and see what happens - can't be worse than I was doing.
