ummm...I don't know I have T-5 lights, but my tank is 30" deep. They both get natural sunlight as my tank is near windows. They are not mobile, but no matter where I put them, they always end up pressed against the glass. No photoshop. It is actually hard to get a good picture of them as they always look fake.
The 2nd trachy was starving to death when I bought him so the secret is just food in general I guess!
The first mushroom pic was taken with flash, and the 2nd was taken without and with the actinics only. It was mainly to show growth (although I do like how moody they look in the 2nd pic). The color really depends on the light with those guys.
