Agreed, that IS a nice setup for them. They should do very well in there. Couple of points..

1. They will eat the guppies so if you use them, be prepared for that. The guppies will help cycle the filter but it will take a long time wit such a small bioload. Over the next few months, make sure to check for ammonia buildup and do water changes accordingly.

2. You can use java moss, frog bit or ducked but be prepared for an explosion of the frog bit and duckweed. Once it is introduced it will be near impossible to remove. Water lettuce works well but has a tendency to die off and needs to be replaced. Pothos will grow well but needs to be rooted in something and has a tendency to melt when exposed directly to water.

3. Make sure they have some hiding spots, plant cover, etc. It gives them a sense of security.

4. If you can, put a few pieces of wood that extend up high above the water line, they will love to climb on them.

Overall, nice job!
