I just replaced the 2 55 gallon tanks I had with this one. The box was thrown away before I got a chance to see what wattage etc... the lights were. I know this is horrible. It is an LED hood if that helps in the least. As far as the goldfish go. I only got them to break the tank in. They will go in a smaller tank I have when I get the other fish. I am glad to have found this place as well.
You said "a few goldfish" in a 37, and that they will go in a smaller tank later?
How many is a few?
