Betta's do not live in puddles their entire lives and only live in them for a certain part of the year. The rest of the year they live in large bodies of water that would shame most of the larger fish tanks owned by people on this site.
Angel51087;1219878; said:my betta has a tank to himself with 4 otos and it is DEFINITELY filtered. Just cause they originate from stagnate water doesn't mean they have to live in it whilst in our care. I have a filter on the lowest setting so it creates only the smallest of currents, so he has "natural environment" with clean water. Would you prefer that or living in your own toilet?
