I don't even know what that is.For every Paul B, there are thousands who buy an Ali express LED light and kill an anemone.
I also don't consider this an expensive hobby at all. If you keep killing fish it can be. I have a 32 year old fireclown and he was probably 10 bucks. So he cost me what? 30 cents a year or something lie that.
If your fish live 9 or 10 years and they cost 20 or 30 bucks, it's just pennies. If you feel the need to change water every week, that could get pricy. I change some water 4 or 5 times a year so it isn't much.
I figured it out once and I think it cost me about $900.00 a year including electricity which is the biggest expense.
