Welcome to the forum !

So you have a betta then another empty 3 gallon tank ?

 

Welcome Brian, I've heard petco's are carrying them and their supposed to get 4"...although theirs some claims that they can reach 7" which I highly doubt.

3 gallon, I'd stay with something small...equipment requires room (heater, filter) and doesn't leave much room for fish besides something such as a labryinth (sp) like a betta sadly.

 

welcome.

 

welcome brian! yeah i wouldn't put anything else but a betta in a 3 gallon...also i heard petco is having their $1 per gallon sale tomorrow, at least in my city in MA. you should call your local petco and check it out.

 

A couple male Endler's would work.

 

Welcome Brian!

If I was you, I would go for the betta too, just to be safe. I find that most other fish will need airstones or filtration. Like others said already, it'll take up space.

 

eh, go 55g if you can get it through the $1 per gallon sale. You'll be happier, have more options, have more room for "error" per say, and you can probably score equipment used through your local craiglist or ebay.

Endlers are similar to guppies, both being small...colorful if their males for the majority....and can get by in a smaller tank IF it's heated and has oxygenation/filtration.

For tank maint. for ANY type of fish you pretty much need/require the same basics...a heater that'll help keep the water temp stable, a form of filtration- sponge filter, hang on back filter, canister filter, in tank filter, and some will say proper lighting (but I consider that moreso just for YOUR personal viewing pleasure). That'd be the bare minimums one can get by with. Even MY betta is kept in a heated tank (although you'll read that many will say they don't NEED a heater...I tend to find they do better WITH a heater).
.................................................beyond equipment you need to do regular weekly partials usually using a siphon and drawing the water out from the bottom of the tank (roughly 25% should be removed, but can be more) and adding a good Dechlorinator such as SEACHEM PRIME according to bottles direction (I dose for entire tank size and NOT just amount that you removed) BEFORE adding "clean" water that's as close in temp to the main tank as you can possibly get it. I have IN TANK aquarium thermometers with probes that help me assess the incoming water temp and existing tanks temp (tom temperature alert).

And then you have your filter maint. (which varies but at a minimum should be rinsed out once a month removing the gunk, and replacing the media as needed-- cartridges are usually weekly-monthly depending on how much you feed).

PS. guessing you might not know much about tank cycling I'd add a so-called instant tank cycler such as Tetra Safe Start and always have a freshwater master test kit handy for cycling and problems--> Api Freshwater Master Test Kit (always go for the liquid test kits..more accurate).

Breeding depends on what you stock the tank with (and the size of the tank will have alot to do with it on whether or not you "somewhat safely" have room to deal with breeding).

You can avoid it if you have all males in the tank, but most females (like when you buy livebearers) when sold are already pregnant/insem.

IF you have a compatible breeding pair and your water parameters are optimal in addition to your water quality "most" breeding pairs will breed and with most species you can just let it occur naturally or simply seperate the "pair" if you want to prevent it in addition to simply just getting all males (but the key to this would be proper sexing of all purchased fish...which with some species is difficult if not impossible to do).
