Thanks for your advice, I am actually completely new to having a fish tank, I used to have my betta about 5 years ago in a large bowl with no heater or anything, he lived a long time and was pretty happy I think.
This time I went for a second betta and ended up getting 2 because one had fin rot and looked so bad in that tiny cup so I brought him home too.
I got a 10 gal tank and since I was studying architecture I had a lot of left over materials, one of which is the corrugated plastic, I made sure to wash it really really well, also in a lot of hot water before placing it in. I got the heater because I needed to make sure they would stay warm. unfortunately I am unemployed at the moment and cant quite buy all the right things for them, but I will make small notches in the divider to allow for heat flow/distribution. I didnt know about how much water I should give them since I dont have that many places for them to hide in, but I will definitely add more water and move the heater.
About the nuts? I am a bit confused, not sure what you mean, or what am I supposed to do... if you can please explain a little more, I appreciate it.
(by the way I am a girl not a guy, sorry my username is a bit misleading, but no worries)
Would this be a good filter for my tank, and safe for my little guys?
