Yes, just add tank water in, I do anywhere from 1 tsp - 1 tbsp at a time, and wait about 10 minutes between each. The best way to add and remove water (in my opinion) is with a turkey baster. Super simple and easy, not too stressful on the fish. Make sure to acclimate to tank temp, too, before releasing him in the tank. (Will you be able to float the jar in the tank?)

Can't wait to see him!

 

Elleth has it right.

Condition the tank with Prime.

A bag is usually easier to float in a tank than a jar. Leave him in the floating bag. Remove a shot-glass full of water (dump it) and replace it with tank-water every 10-minutes or so. Do this for an hour. Then empty (dump) most of the water and release the fish into the tank by sinking the bag.

 

I'm just wondering, a lot of guides say to net the fish and not to dump any water into the tank due to the possibility of it carrying disease. Do you only say that (the part about leaving a bit of water and putting the bag in to release the fish) because bettas have delicate fins so you shouldn't use nets, or have I been misinformed? Or something else?

 

It also helps if the net is wet. You don't want to put a fish in a dry net.

 

Eh, I just add so much new water and remove so much old over the period of acclimation time, that I doubt there's any old left by the time I am done. But I do usually take at least a couple of hours doing it.

Something I forgot. I add Prime to the old water when I open up what the fish is in, to take care of ammonia levels right away. I also add a f few drops of methylene blue (this is part of how I'm sure to get rid of all the old water).

 

Prime doesn't get rid of ammonia. It only locks it into a harmless molecule for a short period of time. After 24 hours, the molecule will start to break down and the ammonia is released back into the water.

 

I know that. But the fish is only going to be in the old water a few hours, so it doesn't matter. The Prime is just to lock it in so it doesn't hurt the fish while I'm acclimating. The new tank is full of clean water with no ammonia in it.

 

Thanks everyone! I'll just keep him in the bag so he can float (the bag won't sink will it??) I unfortunately don't have a turkey baster, is there another way to remove the water?

I do have a soft net and a jug that I can dump the water into after he's acclimated. How long should it take to acclimate him?

 

One can be as fussy as one wants when acclimating. I know serious keepers that match the temperature with their finger, check that the pH is within 1.0pH points, remove most of the bag water (easy when it's in a bag) and dump them in. Acclimating protocols seem to be as much for the keeper as they are for the fish. And opinions vary widely.

Roll up the bag rim and tape it to the side of the tank. By the time you replace the bag water -- shot glass by shot glass -- the bag water is diluted enough to be safe and the pH is matched.

Any pathogens came with the fish. So it's only a concern for a community tank.

I just dislike using nets on fish. The stress ain't worth it, in my opinion.

 

Alright, so I'll take out a teaspoon and put a teaspoon in. We also have little paint droppers that we can thoroughly wash out to remove the water. Should that take about an hour? Maybe less, I'll want him out of the bag as soon as possible.
I've used that netting method on my fish before, and they seem to do fine with it, I pour them into the net right beside the tank so transferring is quick and easy. Thanks everyone for the help.
Super excited about Mordin coming!! I just hope the tank comes in time!
