Hello there!

My girlfriend lives in a dorm where the only pet they can have is a fish. We probably got this betta fish a year ago and he's been through rough times. He's in a 1.2gal tank and has severe fin damage. He's not really active and I feel like he has no room. It makes me really depressed. She doesn't regularly clean the water out of the tank and since her campus is far away, I can't be there to do it myself. I'm only able to visit maybe once a month or so.

I'm getting him a 2.5 gal tank, but I'm stuck on what kind of filter to get for him. I was contemplating if it's better to get a sponge filter and pump

or get a HOB with a pre-filter sponge

(or even find a sponge filter to use as pre-filter sponge)

With just the sponge filter, I'm unsure that it wouldn't be enough filtration overall in the tank. With the HOB, I'm concerned that there wouldn't be enough beneficial bacteria growth on the pre-filter sponge (unless I used a decent sponge filter as the pre-filter sponge.)

I have pretty good knowledge of the nitrogen cycle and chemical interactions, I think I'd be able to establish the tank before putting him into it. I know that'll be hard to do and upkeep in tanks smaller than 5 gals. I'm sure that she can manage partial water changes bi/weekly and I could do full water changes whenever the tank needs it.

The only other thing I'm thinking about is IAL/Tannins and how that'll interact with a cycled tank. I want to see if it'll help with regrowth of his fins. I tried doing aquarium salt treatments for several days and it didn't help at all in the long run. He's lost about 75% of his caudal fin and it makes me want to cry when I look at him. He is still grumpy so I guess that's alright.

Thanks for reading. If you have any thoughts or suggestions, they would be greatly appreciated

A 2.5g is not any harder to cycle than a 5g. The procedure is the same. I would recommend putting him in the 2.5g as soon as it's set up and doing a fish-in cycle. Use the API freshwater master test kit to monitor toxins. Here's the drill:

Change half the water whenever ammonia or nitrite approach 0.50ppm. Dose Prime water conditioner @ 2-srops/gal of tank size with changes and 1-drop/gal daily until cycled. The tank is cycles when ammonia and nitrite read 0.0ppm and nitrate increases slightly between changes.

Many of us recommend using Tetra Safestart to speed up the cycle.

The Azoo Palm is a frequently used HOB for small tanks. They also make a good small sponge filter. Foam Aquarium Biological Filters: Azoo Oxygen Plus Bio-Filters

The Palm can be found on F&S too.

IAL/tannins have no effect on the cycle. If your fish has fin issues, it's highly recommended.

Azoo palm (hob) or Jardin mini cylinder (sponge filter) would take up less space but still give sufficient filtration. Your linked sponge filter is really bulky for that size tank. I've sued and loved whisper 10 air pumps, usually wrap in towlel/cloth/blanket to muffle vibration.

AA is right. That Jardin double sponge is very large and way ob\verkill for a 2.5g.

Look up the Azoo Palm on Dr Foster and Smith site. Lots of small-tank keepers are happy with those. Plenty enough sponge volume for bacteria and easier for a novice to run and maintain.
