I'm new here and I really do apologise if these questions have been answered elsewhere. I have spent the last few days reading through the stickys but I'm still a bit confused. I've kept goldfish before, but never tropical fish so I was hoping I could get some specific advice.
I'm being given an ex goldfish tank, its about 12-13 litres (which is about 3-3.5 gallons?). I thought this would be a great opportunity to get a betta.
So I need to buy a heater. A lot of the ones mentioned on these forums are brands I can't find here. This brand seems to be quite common here. I found this one:
Is anyone familiar with it? Is it suitable for my tank size? At the pet shop they showed me one where you can't adjust the temperature which I thought was weird? Also, it's coming up to summer soon and my flat gets really hot in the day. I'll be at work so I won't be able to check on the fish. I'll make sure to keep the tank out of direct sunlight, but will it be dangerous for the fish if the room gets too hot?
My other question is filtering. The tank comes with a pump and air stone. I remember with the goldfish, the pump was pretty strong and agitated the water quite a bit. The pet store told me my tank is too small for a filter as it would make the current too strong for the betta. They also said filters are not necessary for betta anyway as an air pump is sufficient? I thought an air pump and filter were two completely different things. I was thinking of getting a sponge filter instead:
I read that they are safe for baby fish, so they must be ok for bettas. If so, which size of these would be suitable? I've also read mixed views about their efficiency though. I am so confused as to what to do. Should I scrap the sponge filter and just get a gauge to limit the air supply instead?
Lastly, I know it's a personal preference on whether to do a fishless or with fish cycle, but which method is best for a betta beginner? Approximately how long should I expect it to take with my tank size? (I want to make sure I don't rush it).
This is the most informative place I've found online yet for bettas. Sorry about the long post, I just want to be prepared and make sure everything is set up properly before I get a betta :). I was eyeing a beautiful male with gorgeous maroon/red veil fins yesterday. I can't wait!
