I have seen them at the petstore and in magizines. Do they do a good job. Are they basically like moonlight, like will nocturnal fish come out if only these are on. Also how many do you think I would need for a 55 gallon long.
Not only will your nocturnal fish come out when they are on, its hard to describe how incredibly cool they look! They had them set up in a local fish store here in town, Id seen them on line and all and never thought much of them but after seeing them set up in an aquarium, I was sold on the spot. Basically in my 125G tank Ive got 3, each pointing down onto one of my rock structures, with a 55G I bet you could do 2 and it would look incredible. The blue and Green go very well togeather. Only thing to remember is that there are 2 things you'd need to buy for these, the lights, and the hub. Basically what the hub is, the lights plug into the hub (up to 3) the hub plugs into your wall socket. Paid $10 for each light at the LFS here and $12 for the hub. After getting them set up I can tell you, money WELL spent. Looks amazing
