Giant Danios

[425nm]

Hey guys.

So I've been trying to breed some giant danio with little luck. They were spawning back in April though in low quantities (ie. 12 eggs per pairing) and all the fry came out deformed & died after a week.

I was wondering if anybody has bred them in the past and if they have any advice on how to get them to spawn.

I've been using breeding traps in and out of tank as well as just using mesh over the bottom of the tank. Should I be pairing them or setting them up in groups?

Telling the males from the females is also proving quite difficult.

Really? No one has anyideas?

did you buy all your Giant Danios from the same place? It's possible they're just too imbred to produce normal fry?

Sexing them is an issue, but if you knew for sure that you had a male and several females, then letting them spawn in a heavily planted tank and removing the adults to allow the fry to hatch you might have more success with them living (if they're not deformed).

i've personally never bred them, but it's what i've heard through the grape vine...lol

Apply this advice to any egg-scatterer; still the best way imho

, , , usually how I end up with fry from any given egg-layer - including my danios.

BTW - with an under temp. water change the danios stress(?) and flush their colour. When they are washed out like that I regard some of them are grey/silver whilst others of the same brood retain a 'fleshy' pink colour.

Is this a identifying feature between sexes? - I do not know; and also cannot spot any differences otherwise.
