The Glowlight Danio is both beautiful and striking, and a school of them in a well-designed tank is unforgettable!

Hi I think all the information on Glowlight danios (danio Choprae) is flawed. I bought 2 of these in spring 2013 to create a mixed danio school to go with a tank of platys. Over the years the other danios slowly died off (pearl, leopard, albino/normal zebra danios) and at 5.5 years after purchase the breeding pair of danio choprae were looking a little lonely and becoming territorial. I added some more of their species to give them a proper school and they went back to their normal behaviour of chasing other danios. I think the old male couldn't out-compete the juveniles as they matured and became interested in the old female and he gave up at 6 years old. My female is still going strong at 6.5 years old. Oh and they have been about the same length as the platys for some years now. The female is the longer but the male was about 2'/5 cm and she is 5.5 cm

WOAH, your 32 gallon tank is way over crowded! Even if you just had the danios in your tank, it would still be over crowded. When stocking your fish tank there is one fundamental rule. An inch per gallon. For example a 1.25" glowlight danio needs 1.25 gallons of water. Please remember this rule for the future.

    Your using the rule incorrectly, a 4 inch Red Tail Shark would need at least a 4 foot long tank, a 55 gallon. Glow light danios need at least 20 gallons.

    This is not really a rule but more of a guide. Not always correct with all fish. Some fish it is more important to have length then actual amount of water. a 55 gallon high tank for example would not have enough surface area for many fish, where a starndard long 55 gallon would.

Hey, Kyle, that only applies as a GENERAL rule. If you have many live plants you can support a higher bioload. If you have superior filtration you can support a higher bioload.

Love that fish, have 8 in a 29g heavily planted tank together with odessa barbs and a red-fin shark.
Very active, always on the move, swim mostly at top-middle, enjoy swimming against the current from the pump. They do not seem to be as shy as the article describes - even though barbs try to chase glow-lights once in a while, danios easily outrun them and continue to swim as normal. Sometimes i can see danios "fighting" with each other - circling around, trying to get the opponents tale, but no harm is done. I believe it is a part of courtship.
I bought mine for as little as $3 per fish, though very few stores carry them.

I have about 50 of these little guys in a 32 gallon and they are insane. Together they get along well with 2 boseman rainbows, 1 austrailian rainbow, 2 roseline barbs (my fav's), and 7 golden white clouds. Heavily planted, they have so much fun swiming through the plants & wood; 8 mossballs (giant) at different levels off the wood & plants, with plenty of flow.
