Dianema: Greek, di = two + Greek, nema = filament
When kept in an established group this catfish can often be seen swimming in a shoal in mid water. They are very peaceful and they look great in a group when housed with other peaceful fishes.
Use live or frozen daphnia, cyclops, blood worms, glass worms and similar for the main part of the diet and supplement this with a good quality flake food or suitably sized pellets in order to ensure a balanced diet.
Dianema urostriatum are reliably peaceful even with very small fish. They can be kept in groups with their own kind without any problems, in fact they do better when kept in a group as single specimens tend to be a little shy.
When adult the females are heavier in the body than are the males.
Dianema urostriatum has been bred by hobbyists but there is no verified account of this. Breeding this fish is still regarded as a serious challenge.
Wild populations of Dianema urostriatum have not been evaluated.
Dianema urostriatum is a little delicate until it has been acclimatised to your aquarium. If losses are going to occur it is normally soon after the fish has been introduced to the new tank. Keeping the water soft and mildly acidic seems to help to reduce any potential losses.
