Here's my grouping of nanos. It started out innocently with a Petco nano, then 2 Petco nanos. I couldn't afford not to buy two. Then GWAPA started a competition so added a 2.5 gallon. And dug out the old 2.5 hex nano for crypts.
Here's all four. I really should find a more artistic display for this, but it's easiest to feed and fert and light all together.

Closeups of HC growing in HOB nano filter. I have a struggle to keep this alive. So until I come up with the correct environment, I'm keeping it alive on the filter.

2.5 hex with crypts - 2 pictures of it
