Like many South American annuals, they are generally brown fish, but with some very subtle irredescent colours too. The tail of the male flashes between yellow and blue – getting a photograph that captures the delicate beauty of a fish in motion is next to impossible.
I’d not kept Austrofundulus guajira before, so I read up a bit about them. The males can be a bit aggressive to the females apparently. I set them up in a 12″x12″x18″ – fairly sparsely set up: filter, tub of peat to spawn in, water sprite and java moss.
The advice I had read was to keep them together for short periods only – just to allow spawning. I initially separated the pair every evening, the female’s caudal fin did get nipped a bit, but this only seemed to happen when the fish were first put together each day – keeping the fish apart was actually making life harder on the female!
After a few days I decided to stop removing one fish, which was a good move; now the pair happily spend their day hanging out together. I have never seen the female attempt to hide!
These fish are certainly hungy eaters. They lunge at their dinner – whatever it is – even jumping out to get food I haven’t quite put in yet
They are being fed a diet of whiteworms, small slugs, flake, fruit flies and redworms. I would imagine, by the amount they eat, and the vigour with which they eat, that these fish will be growing for some time!
