Is there a light on this at all or is it just sunlight? This is a very nice example of a low-tech tank. I love the way the crypt has grown in. And im assuming you moved all of the DHG?
Yes, There's light... 2 spiral CF..
I tried sunlight in the previous life of this tank... It got swallowed up by clado.
The DHG died off... They don't like low-tech.
