I just got my new betta, Casey, 4 days ago. I temporarily have him in a 1.5gal tank for the time being until I can purchase a larger one. Ever since I took him home he has been glass surfing constantly, rarely venturing into the middle of the tank. I had a plastic plant in it but every time he even touched it he would dart out and spazz out, and his fins would clamp. So I removed it, and this morning I purchased two silk plants and put them in. He still did the same thing, flipping out every time he touched one. So now hes back to constant glass surfing and the occasional tail biting. I took a super close look at him after putting in the plants and I see now that he is developing stress stripes. My avatar is a picture of Casey, and in that picture he hadnt developed the stress stripes yet. Since I definitely wont be able to buy Casey a new tank for a couple weeks, what should I do for now to stop the tail biting, constant glass surfing, and anxiety??
