I have gotten a 2.5-3 gallon critter keeper type container (with lid) for my betta.
I will not have a filter but do have a heater, thermometer, some gravel and a silk plant. It's not super glamorous but this fish was dying in a little dirty barren betta bowl at the pet store and I couldn't help myself.:(
He's active enough now but is having a hard time keeping food down.
Could I have some advice on water changes, how often, tips and when to completely "scrub" down tank?
Any other tips appreciated!
