what are those beautiful blue fish?
Since a few people seem interested here as well as PMing me about plants/fish.
Hairgrass, not sure exactly what sort, it was too long for my taste.
"Dwarf swords" - (back left) these are too large for a 30cm cube imo. They got out of control and I pulled the tank down because of them. They also start looking ratty after a few months. Maybe if you looked after them and stopped clumping they might work better.
Hydrocotyle something - looks like clover. Not sure which variety or if this is even the right name for it. It was quite awesome. Would use again in the future.
Fish are neons (in the first few images), dwarf guppies, otos and purple harlequins. I have not see the harlequins online before but they are available at quite a few lfs in Sydney. They look awesome with gold heads/purple bodies and are not much more than regular harlequins.
I tore it down a few months ago to try stems, kinda going ok I guess. Have some BBA which is almost gone. This is almost current.. first time trying hc, happy with progress to this point
The thing on the left is a device for hatching brine shrimp. My work is currently running a kickstarter for them. Check us out here
