Cycling 2.5 for quarantine tank

I’m trying to cycle a 2.5 gallon for a quarantine tank, and I want to know if it takes longer to cycle a bigger tank, and shorter for smaller. Bc I need it soon. So does it take as long for a smaller tank?

Normally it will take about the same amount of time to cycle a small tank as it does for a bigger one. Do you already have a cycled tank? If you do you can take some media from the cycled tank and put it in this tank when you need it.

The worst case scenario with an uncycled tank is that you have to do daily water changes to keep the Ammonia and Nitrites at bay. The small volume of the QT makes this even more important as the ammonia concentration can spike, depending on the fish you plan to move into the QT.

I have a cycled 20 gallon. I have some stuff in the cycling tank from that tank: some gravel, moss balls, Anubias, fake plant, head statue thing.

one betta. Her tank is still getting ready so she’s living behind a divider in the 20 g, but I want to get her out Bc I have another betta in there, and I think he can scent her and it’s making him more aggressI’ve to tankmates.

Those things will have bacteria on them so should help this tank cycle a bit faster. If you could spare some media from the cycled tank it should actually cycle this little tank right away and you can go ahead and move your little girl right away. Just keep a close eye on the parameters and be prepared to do water changes if ammonia shows up.

things can go bad quickly in a tank this small so if I were you I would run the ammonia test daily for a while after you put her in there.

I will! one of my tetras has some kind of weird fungus tail stuff so I might move him in first.

That may be best. Hopefully by keeping the water as fresh and clean as you can will help take care of whatever it is.

Will be setting up a quarantine tank soon for some new fish and hoping to just pull one of the two sponges I have crammed into my filter to help the qt cycle. May also take some of the matrix stones from my current filter. If all of those things are properly cycled it should essentially instant cycle the qt?

Update: first I moved my nerite snail in, then a couple days later the betta who was behind the divider. The ammonia and nitrites are all 0.
