I have an eclipse 5, but not a hex, the bowfront type. It is a neat little tank, but for planting it kinda sucks. The light is in the front half and the horizontal filter is in the back half, so the light is kindof cut off, leaving the back half of the tank kinda dark. The filtration is great though for a tank that small.
In mine, I have about 2 dozen common guppies (very small) and about 4 ghost shrimp. It has baby's tears, java moss, 2 different crypts, a small sword plant from my old tank which I forgot the name of, and some java fern. I put the java fern and java moss in the back because the lighting is so poor. I am also trying out some sunset hygro back there just to see if it survives, because I heard somewhere it is nearly invincible.
This tank is still in the "experiment" stages, where I am seeing what grows in it, so it hasn't really been set up in any kind of cool arrangement yet, but I will when I find out what survives the best.
Two 1 GA desktops, a 5 gallon, a 2.5 gallon, a 10 gallon, a 20 gallon, a 25 gallon, and two 75 gallon tanks, all planted.
I am an expert on algae, so ask me if you have questions. I know how to grow it, just not how to get rid of it.
