Golden Black Widow Tetra Gymnocorymbus ternetzi


This is one of the more popular tetras, very hardy and peaceful. An active fish that schools in open water, they are an ideal fish for community aquaria. The Golden Widow is an aquarium-bred strain with a golden body colour, some specimens may also show black speckling. Maximum size is about 5cm.

Tetras are considered easy to keep in a community aquarium of at least 20L, with a pH of 5.0–7.0 and KH of 1.0–2.0. However, they will not tolerate dramatic changes to their environment. The Tetra can live 10 years or more with the proper conditions. They tend to be timid and, because of their small size, should not be kept with large or aggressive fish who may bully or simply eat them.

Fish that mix well in an aquarium are other types of tetras, and other community fish that live well in an ideal Tetra water condition. Mid-level feeders, they are best kept in schools of five to eight or more, for the "shoaling" effect when they move around the tank. They shoal naturally in the wild and are thus happier, more brightly coloured, and more active when kept as a shoal as opposed to singly.

Tetras are best kept in a densely planted tank with subdued light and an ideal temperature of 20–24?C to resemble their native Amazon environment. Tetras are omnivores and will accept most flake foods, but should also have some small foods such as brine shrimp, daphnia, freeze-dried bloodworms, tubifex, and micro pellet food to supplement their diet.

Great purchase
Received them and they looked very sad. They were floating on their sides and I thought I was going to loose them. Put them in the tank and they picked up except 1. I expected to find it dead in the morning but to my surprise it was as healthy as the rest of them. Must be hardy fish cause I thought I was going to loose them all. Thanks

My Gold Widows and Black Widows safe arrived with no problems
Great fish, recovered quickly after shipping. I acclimatised them in a bucket for half an hour adding water from my tank slowly, then placed them in my tank, they settled into my aquarium well with no problems. They all started feeding same day I received them. They were pale when I got them, and I couldn't tell the difference in colour between the gold's and the blacks at first, but after a short while the colour came back and they seemed quite content in their new tank. Very happy with the purchase.

love the fish and this store!
Thanks for my order of fishies!
All the fish are beautiful and look wonderful in my tanks, they are companionable and so the advice given is reliable.
The all arrived alive and healthy and I haven't lost a single one. The order's arrival in WA only a couple of days after ordering was magic, the packaging kept them safe and secure.

My favourite tetra by far!
Beautiful looking colour under my light! I absolutely love these littles guys. Seem to prefer hiding in my plants, but havent even had them a whole day yet. Only regret was that I didn't order more than two!
