I recently got a new 5 gallon tank from Petsmart today to replace my poor lil bettas 1/2 gallon tank he has been in for a little bit. sadly he was a table decoration at a formal dinner/party at a hotel and i just snatched him home!
I had a few questions about my new tank, it came with a huge filter (it was a topfin 5g aquarium kit). As soon as i put him in, the current made him flow around and he actually got sucked in a little bit into the filter so i quickly unplugged it. Now i'm wondering how to alleviate this, both the current and suction. Am i better off getting a filter maybe made for a 1-3 gallon tank? (i'm using one in a 1.5gl tank for my crowntail till i get another new tank) and the current and suction are no problem.
also, if anyone has any advice about heater fluctuations, because my room is always at 50-55F (cold room combined with cold California weather). The new 5gallon tank has an adjustable heater so it stays at a constant 78degrees area. but the 1.5 gallon tank fluctuates 2-3degrees during the day sometimes more if a heater is turned on, any advice?
