My son got a Betta for his birthday We purchased at PetSmart, and they don't seem very helpful, we get a different answer about everything everytime we go in there. I am going to answer the questions here, and if anyone can help I would appreciate it. He is a red betta, and he has been very active until the last couple days. he has become very lethargic, and is not eating at all. He hangs out in his (plastic) plant and doesn't seem to want to swim around at all. he is hanging out at the bottom if he isn't in the plant. He is in a small tank, no filter, no heater, according to PetSmart employees that wasn't necessary, but I am beginning to wonder. Now that it is cooler in the house maybe it is affecting him. Please help!
