Hi everyone. I'm writing here because I'm worried about my betta.
I got him around 2 weeks ago and he's in a 5 gallon aquarium with an adjustable filter.
I was told by the people at the shop that they don't need a heater but then I did some research and found out that wasn't true; so I bought him one two days ago plus a large plant to match the smaller one he already had.
Since I put the plant and the heater in, he sits on the plant or at the bottom of the tank a lot. He looks healthy, eats, flares up and swims just fine. I test the water every day and the parameters are perfect and I cleaned the gravel and did a water change (35%) yesterday. But he still just lays on the plant or the gravel as opposed as before when he would swim back and forth all the time. I've been told he's just resting, but I worry about him constantly so I'd like to make sure.
Do you think he's okay?
