Lifespan list

  • We are currently upgrading MFK. thanks! -neo
I would reckon fairly long as a rule slower growing fish (and other animals )tend to live longer,than many faster growing species,based on growth rates and adult size I would say a datnoids could live into its sixties.

Oh yeah,agreed on the long lived slow growers.I give them well over twenty years....
 
I plan on making a complete more organized list later when I have more information.
K krichardson there is a way to get better growth from dats that are young,that also makes them more stable: set them in a outdoor pond from mid spring to late summer,make sure the pond has vertical growing water plants that reaches the surface,under these conditions expect to see roughly a inch a month if u start with 1 to 21/2 in fish

I would try something like that if I lived in a year round warm area.In fact,after reading of the benefits of natural sunlight I have actually placed a few troublesome African cichlids in my yard pond for the summer a few years ago and they did well.
 
Where did you get the info for the bettas?

A guy at my lfs breeds them and when I asked him, he said between six and eight, with his longest lived being 7½ years.

11 years is an extra four to five years on top of that. :)
 
One problem with young dats is they usually don't feed as actively as cichlids do and it might take a little more than simply dropping pellets into the pond for them.
 
The betta belonged to a friend who claimed that the secret is to feed very little,like 3betta pellets a day,personally I think bettas do best in community tanks with more room,I regard twenty gallons as the minimum for long term health,and a college study showed bettas who exercised more lived significantly longer.another friend of mine kept his bettas with guppies,a glolite tetra,a face,black window tetras and a Chinese algae water.

Ahh yep. 11yrs sounds like a long time...

My old betta Bruce lived his life in a 120ltr community tank and lived off of NLS, I had him for just over 3½ years but got him full grown from a chain store so idk how old he actually was. His mouth was droopy from being in horrible conditions and if he had of stayed at the store any longer, he probably would of been dead within a fortnight.

My current betta Miles has a little 50ltr atm coz he's tiny and my hubby is going to build him a "betta" tank (<--- sorry, I like puns) close to 140ltrs for when he gets bigger. He also lives on 1mm NLS thera+a (crushed coz he's to small to eat them whole atm) with the occasional bloodworms or brine shrimp or whatever else I find out that he likes as treats...

Man if I got 10+ years out of a betta I'd be one happy gal, and own one happy betta. :D
 
Genetics also probably plays a big role,my friend used to have a terribly stunted betta that only grew a little over an inch(even with his long fins) nothing we did could make him grow,I also sometimes see bettas with crooked backs(a classic in breeding problem)

Yeah, Bruce was from a chain store so he probably didn't have the best genetics to start with...

Miles on the other hand is young and came from a little local shop so I'm hoping to get a few good years from him. :)
