Why can't tigers be bred ?

  • We are currently upgrading MFK. thanks! -neo
Well, knowing which ones are the males, or females, won't speed up breeding, in a group. Are yours mature? If so, have you noticed anything by way of potential breeding activity ? And if they are mature, do you try to condition them?
 
Huh ? I don't think anyone is assuming anything - I'm hoping that those that have long term groups, mature ones, can pitch in here and talk about any sightings of breeding activity. It's my philosophy that if a group of fish is kept together long enough, it's a matter of time. (Assuming that conditions are ideal, and that stimuli are created.)
 
There isnt any proof of any successful captive breeding period. At least I haven't. Enlightenment me! I hope im wrong.

The other issue is that to my knowledge, no one actually knows when they ARE mature. Since they're sexually dimorphic (to us anyway), how do we know what to look for? Rays have claspers, some fish change to "spawning" colors. Datnoids don't seem to fit any of those descriptions. The only thing that seems to be a little different on my Datnoids is there anal fins.

The point is - it's just a matter of time, if a group is kept together, long-term, that visually sexing them really isn't important. If you only have one, and want to buy one more, then yes, obviously - like with Cichlids, but with lots of fish, it's just keeping a group long enough, which is what most people don't do, for a number of reasons, and thus, never giving the fish a chance to breed in the first place, since as you said, they may not be mature yet.
The depth aspect definitely could be a factor.

How do u know that will work for datnoids for sure? Yes it may work for other fish like for asain aros. u have a lot of them together and eventually two will pair up and bred.
