Izzy, I might do that. I'm very happy with the bettas I have, but I love to think of what I could do. If I got a bigger tank... 10 gallon? What could I put in it? Fish I have had in the past and liked are guppies, neons, glowlight tetras, mollies, and platties. But I do like the look of danios and glofish.
Again, this is just brainstorming. :)
Oh I love glowlight tetra! A lot of people pass them over in the store, but they're really very pretty when not stressed. Neons are pretty, too, but I prefer cardinals over them. It actually came down to a choice between glowlights and cardinals in my tropical community.
Lol not to be an enabler here, but Petco is having their dollar per gallon sale until the 19th!
To get a good school and some good color out of the fish I'd suggest getting a 20 gal or larger tank that way you can get more than the minimum six fishies per school. In something like a 29 gal you could have a nice shoal of 10-12 glowlights and then a handful of platies to swim in the upper region and even top it out with some cories or otos or bristlenose plecos.
