I think he would do fine in a one gallon as A TEMPORARY set up, but i am not sure how i feel personally about anything less than 2.5 being a permanent home.
Shipping would be $10.95 for the flat rate box, and that is to anywhere, more if you want a heat pack, but that all depends on the weather where you live. It is still pretty warm here right now.
I havent gotten to know Splatter super well, but he is very active, always dancing at the glass for treats and attention. He seemed to get stressed in a divided tank, and that is when he bit his tail, so i am not sure he would do well with community fish. He needs to be alone or with only snails and shrimp as buddies.
If you cannot get him that is fine, i understand. Just let me know so i can put his picture up again. :)
I have a cycled , planted, filtered, and heated 2.5 gallon for one betta, (though it is being maintained by a temporary nerite snail to keep it cycled), and a 6.6 gallon cycled, planted, filtered, and heated bookshelf tank waiting for a betta. The betta in the bookshelf tank would share his home with 6 kuhli loaches and 1 mystery snail.
In my opinion, pets are a choice and a responsibility, whether fish, bird, cat, or horse, and in our household they are cared for as a member of the family. I don't think an animal should be brought into one's home if one is unable to provide for that animal's needs in full. All of our tanks are fully cycled, planted with live plants and driftwood, and aquscaped to create as close to a natural setting as possible, which varies depending on the tank/inhabitants.
I think it's great that you're being honest enough with yourself to recognize that you are no longer able to provide the kind of care that you want (and that your fish deserve) and that you're being responsible about finding them a suitable home - rather than tossing them at anyone who will take them. Kudos to you for making a tough decision during difficult times for yourself.
