psycho-in-hate asked: Hi there! I'm a beginner at keeping betta and I have a few questions, I have a male betta living in a 5 liter tank with smooth river rocks and silk plants, I don't have a filter and a heater as the water temperature here is ideal and doesn't drop down low, I changed my tank weekly and was wondering should I bought a filter ? also is it wise for me to add tankmates? thank you!
I would always add a filter!
And with tank mates it’s a bit more of a challenge, for example I had several betta fish that could only be housed alone, and then again I’ve had bettas that do great in a community tank. If you’re planning on adding more fish I would have also set up the community fish first, and then introduced your betta.
I really hope they meant 5 gallons and not liters? 5 liters is 1,3 gallons, which is not suitable for bettas nor tankmates. Buying a filter would be of no use.
I agree with aquariadise that 5 liters is far too small. When I set up a tank for a betta, I use minimum of 5 gallons. The tank needs a filter, but low flow, so use either a sponge filter with air stone or an internal filter that can be adjusted to a very low flow. You will need a heater, too. Bettas get sick over time without a heater.
