I recently decided to purchase a betta. I am attracted to the minimalism of having a relatively small tank with a single fish in it. I have no experience with fishkeeping, so I've spent the last week reading through a bunch of old threads. This is a great forum, and I've learned a lot. I do have a few quick questions though.
I plan on getting a 5 gallon tank with a filter and a heater. However, I've read about cycling and decided I'm not going to do it (sounds a bit complicated for my very first aquarium.) So...in a 5 gallon filtered tank with a single fish, how often should I change the water? Based on what I've read so far, I'm thinking a 50% and a 100% per week would be adequate? I'm planning on buying a testing kit, because I'm anal and will be very worried that I'm poisoning the fish.
The idea of doing frequent 100% changes doesn't bother me, but will this stress the fish? It seems like being removed from the tank once a week would be harmful.
Also, since I'm not going to cycle, should I even bother with a filter? If I'm going to have to perform frequent 100% w.c.'s anyways, is there any benefit to be had by purchasing a filter? I have read that it helps the heater heat the tank evenly, but I've also read that bettas prefer still water.
Thanks in advance for the assistance!
