Got a call from one of the rest homes today. They have brought a fish tank and some fish and were looking for someone to tell them how to keep fish correctly.
They have bought a 200L and so far stocked it with a mix of real (one of which isn't aquatic, despite being purchased from a lfs) and plastic plants, a clown loach, 8 guppies, a golden algae eater and 2 gouramis (which turned out to be Boesemanis). They eventually want angels but will now wait for the tank to cycle (a process they knew nothing about but do now and understand the idea).
The residents are all very pleased with it and apparently several of them have kept fish in the past and were keen to have some to look at.
