Oh my goodness, I'm so excited to finally have gotten to do this. When I'm not at school, I work at a vet clinic that my mom owns. A few years ago, before I was really into fish, one of the technicians got a betta and set it up in the lab area in a little one gallon tank with one little plastic plant. Since I got into fish keeping, and more recently bettas, I've been nagging my mom to let me upgrade the tank to something more suitable, and she finally ok'd it (probably doesn't hurt that the tech that got and took care of the fish was recently freed to pursue other oppertunities and we therefore don't have to worry about "offending her fish keeping abilities"). While I realize that a 1 gallon is arguably accepable for a betta, the goal was to put together something that's easier to take care of, and maintaining stable water perameters is way easier in a larger tank.
So here's the original tank in the lab area. No heater and only one (sharp) plastic plant, one 100% water change once a week.
And the new tank located in the doctor's office. 5.5 gallons, uses a (baffled) Marina s10 Slim filter, heated to 80*, and is fully planted with fast growing, easy to care for plants. I also picked up some Omega One Betta Buffet pellets to replace the crappy junk food they had been using. If I'm not home on a weekend, I'll be instructing someone there to do the required water changes and fertalizer dosing.
lol I'm now known as the fish nazi, as I refuse to let anyone put any more fish in there. You should have heard the suggestions - neon tetras, male guppies, and I nearly screamed when someone asked about a goldfish.
