My fiance was pretty unhappy when I started on this betta adventure, too. He seems to be warming up to them. I had him feed them a couple of times and he was like "OMG they ate it off mah fingur!!1!" and ever since he'll happily help me when water changes come around and he'll be caught sitting in the 'fish watching seat' watching my girls and guys swim around. Show her they're more than just a decoration. :)
Ever since I started feeding live, my mom is always around for feed time ;) She told me today if once my mollies die if I get rid of that tank, the 20 gallon, and the 1.5 gallon I can get the 10 gallon and keep the (2) 2.5s! 5 bettas, not bad! But I'm thinking of keeping one of the 2.5s as a "sick/QTing" tank because the 10 will be split and I don't want the other fish to get sick, too.
Now, time to get the bf on board.....
