Bettas seem to grow sporadically, but eventually they start looking like mini adult bettas. Males grow fins and start displaying for each other, flaring and even fighting. If you started with a 5 gal as a spawning tank, and have, say, 100 fries, you should have already moved them to larger quarters. They might have been transferred to a 10 gal and then a 50 gal. Regardless of how large your grow out tank is, the young males will soon start taking chunks out of each otherís fins if you donít jar them. So on this page I will cover the (painful) jarring process.

                        
       young males are starting to grow some fins and nip each other: it is time to separate them.
           some spawns are more aggressive than others and will need to be dealt with much sooner. 
          The above  spawn was  especially gentle  and the males  didn't pick  on each   other much.

Jar as soon as aggressive behavior is observed. Donít wait too long, as some severe fin damage may be irreversible. If the fins have slight tear do not worry at that age the bettas mend quasi instantaneously. 

Jar only those males who are fighting or getting attacked. It will save you some jar washing for a few more days/weeks. Heck, if you have as many jars to clean every week as I do, every day counts :)).

Have clean jars ready make sure they are sanitized and did not previously house an infected betta. If you have lots of bettas to jar, you might want to pick 1/4 gal jars. They take less room. If not, I recommend at least 1/2 gal. I hope you were smart enough to stock on jars when you begun the spawning process! If not I'll tell Santa to skip your house this year!

Fill jars with water from the tank it will reduce the stress and shock the young bettas will go into. Of course, in a week, you will do a full water change and give them clean aged tap water. If the tank water is different from your regular jar water, you will need to slowly acclimate the jarred bettas to the new water BEFORE making a full water change!.

Keep jarred bettas near each other to avoid them going into depression. Allow them to see each other, place them next to each other. Bettas at that age are used to be surrounded by their siblings and a sudden isolation could throw them into a bout of depression. I personally don't jar my bettas, I use custom built large bungalow that float inside the tanks. This way they can still see all their siblings :)). It works great.

Newly jarred bettas might sulk and refuse to eat for a few days. If so, give them something they canít refuse, like live worms for example. It will help the morale of the troops :))


Voila, it is pretty simple, I hope this helped and remember: Donít wait until your bettas are shredded to jar them!!!
