I started with a Fluval Roma 90. Since October I have upgraded the lighting from 2xT8 to 4xT5 and added an external filter (a Hydor something 10) which is now running alongside the Fluval U2 the tank came with.
It is very heavily planted (I actually have some thinning out to do this weekend...)
It is currently stocked with
3 dwarf gouramis
4 adolfo's corys
2 german blue rams
6 cardinal tetras
1 bristlenose
1 african armored shrimp
The corys, the rams and the bristlenose, possibly the cardinals too, are going in another tank, more on that in another post, in a more appropriate section.
I have also recently aquired a TMC microhabitat 30, which is currently populated by a fire shrimp, a pepprmint shrimp, three sexy shrimps and two nassarius snails.
