looking really good!
That is a huge tank for bettas.
I think a darker background would compliment a planted tank like that (black even).
edit: what are those? fire eels?
Thanks
i have thought about going for a black background, and may even get round to it at some point. but at least the bark effect is better than the plant effect one i used to have
they are khuli loaches (sometimes spelt coolie) i have 7 of them, 4 of the striped ones, and 3 of the black ones (like the one under the log) they have a reputation for being very shy, and never being seen, but i find if you have enough hiding spaces and a decent size group, that they are pretty sociable, and i also find that the black ones tend to hide more than the stripy ones.
they look really cute when they coil up in a pile together, or wrap themselves up in a plant, (they look like snakes in a tree)
edit: oh, and they need a fairly soft substrate, preferably not gravel. i have a soil/clay based substrate, but sand is good too.
plus i also have a bristlenose plec, who you can just spot in the picture with the black khuli loach, if you look closely.
