These fish are so full of personality, colour and appearance in a package only a few centimetres in size, they are fabulous! And the ones I received were in top notch condition, are wonderfully coloured and growing fat and fast on a diet of mosquito larvae, white and micro worms and daphnia. Not the easiest fish to feed, but worth the 10 minutes extra effort a week to provide the live food for. They will reward you greatly with their beautiful colours, amusing behaviour and their diminutive size whilst appearing to be a fish that should be a full sized package.
I have a small colony of 6 in the tank full to the top with driftwood and river stones, providing caves, nooks and crannies for all and then some, and with a lot of Subwassertang and Bolbitus fern as plant cover and fine gravel topped with a sand cap as these fish like to dig pits and under the rocks. This seems to be working well. The males have all coloured, the females are sticking with their chosen males and aggression and chases are minimalised.
Filtration is with a HOB filter with a sponge on intake, biomedia and a bag of aroginite sand to buffer the pH into the alkaline range. temps are at 21 - 26 as the summer plays with them, but the fish are doing fine. Because of the abundance of cover to the top of the tank, they swim actively at all levels and are thoroughly enjoyable to watch and keep. I will be adding some emerald Rasbora to their world soon :D
