Hey everyone

I have a 50 gallon housing a small tree frog, three newts, and a small brown anole. (i know mixing is a bad idea but i didnt know this when i was buying them two years ago, the pet store guy said it was fine, although ive learnded now that threre not so knowlegable. They all get along fine though). Anyway, i was just wondering what lighting fixture i should be using. I have one now but i was just wanting to get a second opinion from someone

thx, its very apreciated
