I just got my betta a little over 1 week ago and he has a 15 gallon tank all to himself. He is super energetic and I feel like he's always swimming at the front of the tank wanting attention. I feel bad because I feel like maybe he's bored with his environment and that's why he swims at the front of the tank? I just did a 60% water changed because his plants were dying and the leaves I had floating at the top were getting old. I will definitely get more leaves and plants soon, but he also has his coconut, plant hammocks and floating log for his environment. Any suggestions?
