Tika, our betta, has been acting different the past two to three days. He is normally a very active fish and does laps around his 4 gallon aquarium. However, off late he has taken to lying at the bottom of the tank.
He is eating normally, is quick and agile when he does move or go to the top of the tank to breathe. There is no sign of pop eye or fin rot or any of the other betta diseases I have read about. He has just taken to sitting at the bottom. I gave him some betta pellets soaked in garlic juice earlier today.
Any suggestions on what is going on?
