This is a big tank, about 30 gallon. we made it ourselves.
There are only a few pieces of shrimps in this tank, and they like hiding behind or under driftwood.
The substrate system we used for this tank is different from others, as you can see. This is ADA-Africana, plus a little bit ADA-Amozonia 1 on the bottom. ADA-Africana has stronger ability to lower pH. Therefor, this tank's pH is lower than others.
My filter system is easy: a Eheim classic canister + a Bio-wheel power filter.
Jager is always my favorite heater.
One more thing, we use a half-pint container and half teaball net to help prevent baby shrimps being sunking away.
