20 Gal Tank Setup

This is a moderate light, no CO2 injection tank. I use Hagen Glo fixture with 2x24W T5HO fluorescent bulbs and a daily dose of Seachem Flourish Excel. Filtration is provided by Eheim 2213. Substrate is a 1.5" layer of flourite.
I planted Anubias barteri and Anubias barteri petite in this tank. I also routinely plant cuttings from 58gal tank, but they do not grow well and are soon covered in algae. The next time I prune plants in 58gal, I replace plants in this tank with the cuttings.
Cleanup crew includes Malaysian Trumpet snails, 20 Olive Nerite snails and 3 otos.
6 Tiger barbs (Puntius tetrazona) and 3 albino barbs are constantly chasing each other establishing pecking order. Originally the school consisted of 7 barbs. One of the barbs died after being constantly chased by the dominant specimen, I decided to increase the school by adding albinos. So far it works.
The 2 white cloud minnows (Tanichthys albonubes) live in my tanks for almost 3 years. They are ignored by barbs.
