Captive Arowana Spawn on MFK's

[thebiggerthebetter]

Had two spawns last year.

Post #39 http://www.monsterfishkeepers.com/f...aples-fl-two-4500-gal-13x13x4-5.603969/page-4

Alpha male "Alf" has a third clutch in his mouth as we speak, first of this year, even though I raised the water hardness significantly.

Thanks for posting and congrats on the latest spawn

Thanks.

The thing is I was hoping with harder water, they won't spawn. Alf gets too thin for my comfort. Plus there is a third male that has been added and ... let me put it this way - a lot of scales have gone missing from everyone, even female Kinky, which appears to coincide with the start of the season of passion...

I'm a bit envious of your situation. I've actually taken an interest in this species as a breeding project, although there is very little(if any) profit to be obtained...

Baby aros are offered at around $50-$70 at brick-and-mortar LFSs around here. While they can be had for $30 or less from local on-line vendors like snookn21.

Anyhoo, I didn't do much special except my water was super soft for the first two spawns, like KH and GH of 1 degree or less. John Kreatsoulas (snookn21) thought my success was due to the soft water because his is hard and he never could get them to spawn.

So I raised the hardness to about 3-4 degrees.

Will continue experimenting bit by bit.

Do you recall exact spawning date of your last? Have you obtained multiple spawns from one female? @thebiggerthebetter

 

[thebiggerthebetter]

The dates are listed in that post #39 referenced above, to the best I could.

I have only one female, Kinky. And three males - Alf, Freddie, and a new comer Flap. Kinky had three spawns, two last year and one, a bit later in a year, this year.

I'm just trying to compile as much data on known US spawns as possible(and there isn't much). Thanks again for input. @thebiggerthebetter

 

[thebiggerthebetter]

HTH.

Will see in about a month if I harvest anything out of Alf's jaws.

There's a write up in 'Breeding Aquarium Fishes', Book 1, Axelrod (TFH) on the 1st captive recorded spawning of the silver aro in 1966 in Long Beach, CA.
