The riparium is doing good, not perfect but good. I had some random spikes of ammonia (followed by spikes of nitrates) which I assume are due to bad circulation and rotting plant parts. I am thinking of adding a second filter to cope with this (improve circulation and filter media volume). I am currently doing 30% water changes weekly. The few larger fry from the previous batch are growing nicely along with some of the newer batch. It is interesting that even after a month post hatch, the "big" fry are still eating Paramecium when I add them in the breeding box for the smaller fry (although their main food is banana worms)! These are very very slow growers (tank temperature is at 25C which also plays a role I guess)...
