Which fish should I take out?

[Lupin]

There's really plenty of room there. You may consider more surface and bottom dwellers. Rosies and roselines are both mid dwellers while zebra danios are surface dwellers so you are free to add more fish to the surface and bottom levels. Which ones do you like? Ask first before you buy anything else as compatibility must be taken into consideration foremost.

Get some corys!

The denison barbs (pundits denisonii) get pretty big, I have seen them close to 6".

Well I was thinking of adding some zebra botias perhaps or maybe a rainbow shark for the bottom.
