Great info! Thanks a bunch. I knew they required little light. I just didn't know how little. My main concern was having way too much light. I'm so used to reefs I'm used to planning my tanks in this order:
1) What do I want in it.
2) What size tank to accommodate all inhabitants I want.
3) How much lighting it's going to take for them to thrive and can I afford it
Then I start getting the hardware, setting up, cycling, and slowly adding the fun stuff. I didn't plan my lighting first this time, because I wasn't positive I was going to do it as a seahorse tank. Now that I've been reading a lot about them, I'm going to take the plunge. I have the tank and started cycling under low wattage for a couple of weeks. I don't plan on adding any seahorses until I'm 100% sure the H20 quality is good, stable, and most importantly I'm more knowledgeable. I read a book on keeping them probably 15 years ago, but everything's changed in all aspects of the saltwater hobby as a whole. I can already see the difference in philosophy regarding seahorses just from the basic knowledge from reading on here and seahorse.org.
To answer Ann Marie's question, I want to make sure I know more before actually deciding which kind of seahorses I want to ensure I can be successful. I have the 3 reef tanks going right now and haven't lost anything in over 3 years (not counting my hermit eating a turbo snail). I don't want to start now and especially not a seahorse. I would be bummed, but my 6 year old daughter would never forgive me, so I have to get it right.
Finding out about the lighting was just one of the initial steps in my education. So if they don't require much/any additional lighting above ambient, would only 1 watt per gallon of a 50/50 bulb be too much? Or do you guys think that would be ok?
Thanks again for the info and help.
