I'm hoping you all can help... I'm a new betta owner of "Flow" is his name. He's been a gorgeous happy fish until the past couple days. He seems like he is struggling to stay at the bottom of the tank. He looks like he's struggling hard to not just float to the very top. Is something wrong with him? What can I do to help him?
Background info: we have a 50 gallon tank fresh water. Newly setup in the last 4 months. Only other fish are guppys. Fresh water, with a filter and heater. Just been feeding standard fish flakes recommended by local fish store and algae tablet once every 3 days for the one sucker fish.
I know I'm very naive about all this but that is why I'm here. Pls help Flow and me!
