ANY time you buy a fish there is a chance that is sick or will get sick, even if it looks healthy. That is a chance the buyer takes. What isn't fair is returning a fish because someone doesn't want to take the time to heal it. If you adopted a child and it got sick right after would you return it because it was the orphanage's responsibility to make sure it was healthy? No. Definitely a bit extreme, but the point is the same. Making the decision to take in a new life means being prepared to handle the responsibilities that come with it, and accepting the outcome, even if it isn't sunshine and rainbows. Pets get sick, but that isn't a reason to return them, especially if it is just going to be traded in for a newer fish.
Neil D, although what you did wasn't good, you realize your error. Everyone makes mistakes when starting out with fish, or any pet for that matter, even experts. Luckily now you know and won't make that mistake again. So, the priority right now is keeping your current fish healthy and happy. Your fish is healthy now, but disease can strike at any moment. You need to be prepared to handle treating a sick fish, and if you don't trust your abilities to do that, you need to figure out a way to get over it. All living creatures can get sick, and most won't just get better on their own. So you will
have to treat sickness at one time or another when keeping fish.
To get back on point, you are looking for a safe, submersible filter, correct? If you can tell me your tank size I can help you out.
Edit: Just saw it said ten gallons. I have a great submersible filter in my ten gallon that does not pull on the bettas tails at all. It cost about 25 dollars though.
