I use diy ferts and co2 per my sig.
70G in bedroom.
For botia loaches I have clowns, kubotais, yoyo's, histrionicas, striatas,darios and rostrata's. The rainbows praecox with 7 M/5F.

In rec room
My 33G coldwater rivertank for hillstream loaches and brook loaches.
In daughters room
My 15G Tall sump equipped.
This is also my quarantine tank for loaches. The rainbows however breed from time to time hence the breeding trap with fry floating in there.
