Hello all! I'm new here! I have a question about the Hydor Mini Heater (and I'm sorry if this question has been asked before) but I was wondering how long it takes to heat up the tank? My tank is 2 gallons, in case any of you are familiar with it, the tank is 2 gallons and it has a pillar in the middle that changes colors, and it also has some kind of filter that you put an air stone in and it makes bubbles.
Anyway, I got my Betta yesterday, and I'm being more cautious cause my last Betta died and we think it's because of the temp. Right now, the temp is about 71 and I know that's not good so I put in the Hydor Mini Heater, for 2-5 gallons, and the temp is the same. How long does it take for it to heat up because I love my Betta and I want to make sure it stays healthy and safe.
Thanks so much!!!
