2.5g Tank Suggestions

My gf has a 2.5 g tank that she's not using and is gonna get rid of it and since i love my current tank i jumped on the oppurtunity to take it off her hands. Only problem is i have no idea what i can put in there. Anybody have any suggestions on what i can put in there? And should i get a heater for it or since it's so small is that a waste of money?

There are many species of killifish that can be comfortably housed in a 2.5g tank with no heater.

I've never heard of a killifish? Are they a reasonably common fish to find in a fish shop? Also what would be the best way to cycle a tank this small? I cycled my 20g with fish but since it's so small i don't wanna add any fish that aren't gonna stay in there. I guess i could just drop some fish food in there and let it create ammonia.

You could use fish food, pure ammonia (make sure it has no additives!) or even a raw prawn (i.e. uncooked shrimp) to cycle the tank.

Killifish aren't all that common in most stores. One store near me carries 5 or 6 varieties of killi and the species they carry changes on a regular basis. Golden wonder killifish are probably the most common (I've even seen them for sale at Petsmart) but they're one of the larger killies so they probably aren't appropriate for a 2.5g tank.

Here are a bunch of different species for sale:
Tropical Fish for Freshwater Aquariums: Mamfensis Panchax Killifish

A local breeder or fish sold locally will be much less expensive. Also, you may want to avoid annual killies. These fish come from non-permanent bodies of water and thus have lifespans of less than one year.

I looked at the killifish online and they seem pretty expensive. Anything that maybe doesn't cost so much? I'm a poor college kid so i can't really be spening $30 on a fish unfortunately.

I didn't mean to harp on the killifish; they're just really neat, not so common, and can fit comfortably in a tank that size. There are other options, though:

1 male or female betta
A couple of African Dwarf Frogs
2 pairs Endler's livebearers (although they will breed and you'll have to do something with all of the babies)
1 pair scarlet badis
1 dwarf puffer
A small colony of cherry shrimp
A single, or maybe a pair, of sparkling gouramis
A pair of Neolamprologus multifasciatus

i always thought puffers needs a lot of space. I have a 2.5 with a betta in it and a couple of ghost shrimp. For some, the bettas may prey on the shrimp but it all depends on ur fish's temprament

Dwarf puffers only get to be 1" long, so 2.5 gallons should be plenty. The only "problem" with them is that they should only be introduced to a well-cycled aquarium and most will not eat prepared foods and many will only eat live food such as snails and live blackworms.

Personally I like Bettas. A 2.5 gallon will provide a betta with a good home and you can get them for as little or as much as you'd like to pay for them. Just remember, they're fish just like any other. They need to be cared for properly with filters, heaters, and not treated like crap just because they're "hardy".
