I currently have a 4ft, 250 litre tropical tank of about 15 rainbows
dwarf neons
MacCullochii
Melanotaenia lacustris
M. trifasciata
Boesemanii
about 12 ancistrus
2 Siamese algae eaters
Plus I am fish sitting a few tiger barbs, an angel, a chinese algae eater, some pristellas, danios, rasboras and a couple of leopard corydoras.
I have recently set up an 18" 30 litre tank to house 4 dageti killifish one of our members bought by mistake at the Napier auction.
Over the years I have kept a variety of fish (killed lots of guppies) and am thinking of setting up a 4ft African cichlid tank.
