Zebra Danio - Profile

This little small wonder is an absolute delight to the eyes and also a much-recommended species to possess if you are a newbie fish keeper.

One of the main reasons for this consideration is contributed to the fish’s origins.

Danios are mainly found in Eastern India near and around Kolkata region, West Bengal and because of this factor, they are capable of withstanding harsh water conditions and parameters.

These fishes can be instantly recognized by the zebra-like stripped pattern on their body, which usually comes in either gold or silver pattern and in four to five bluish/purple stripes across their body.

Be mindful though, the ones bought from the shops would come in a much lighter shades than the wild caught ones due to their varied diet plans.

Zebra Danio are usually fed on Vitamin enriched live or dry food.

Zebra Danios are very active swimmers and they love to swim, hence it is recommended that they are kept in a freshwater tank with lots of space for them to swim and it is also advisable to keep them in a group of six or more.

They are around 2 inches long with a lifespan of 5 years. The male fishes are slightly slimmer and thinner than their female counterparts.

They are non-aggressive and very easy to maintain fishes.

    Great article and information! I have 3 Danio in my planted tank with a Betta. They are entertaining to watch as they are very active and curious. They are not shy and I can easily hand feed them. Mine have “colored up” since purchasing from local fish store and are on varied diet, but mainly Rod’s Frozen fish food. They will rip the chunks right out of my fingers. The poor Betta has a tough time competing with these little piglets!

    I keep them in a 20 gallon tank with my crayfish. They seem to be the one fish that is too fast for my cray to bother catching AND they don’t bother her when she molts. So in my experience they have been perfect for keeping with a crayfish. Double score!

    They are one of the easiest fish to keep. I used to keep them in a small 20 litre tank in an airing cupboard and a light bulb. They were very easy to breed. In fact couldn’t stop them but they would eat most of the fry. I had to keep lots of bushy plants for the baby fish to hide in.

    For the most part these are very active fish and entertaining. I recently have 2 or 3 that either lost their appetitte and gradually withered away..like they would hardly eat….i read where i thought it might be some sort of TB…I have 1 remaining who seems to be strong and always a fast swimmer…I think he was the dominant one of the group….Could TB be contagious and if so how could i go about testing etc
