I made the mistake of buying a one gallon bowl when I first got the Betta 4 days ago. It was a spur of the moment choice to get him, and I didn't know what I was going to need and more of less guessed. After some reseach I went out and bought a proper tank. A 5 gallon glass. With a Tetra WhipserMicro filter. (on the very lowest setting, barely a trickle) Anyways, I set up the new tank yesterday morning and let it run overnight and got the temp to between 74-76. From advice given from other memebers I placed him in a bag and over a period of an hour floated the bag and gradually added the new water to the bag. He was very inquesitive when he first left the bag, seemed normal. But hes been going "bonkers" for over an hour. Non stop flaring at everything in the tank and hes espically interested in trying to get behind the filter and underneath. The filter has very thin slit on the bottom where the impeller is. hes not being pushed around by the current or sucked up against the bottom, but he keeps going back and fourth underneath it. In his little bowl he didn't move around to much and all this activity has got me a little worried. Also, there is a background on the tank... is that good or bad? It seems to be upsetting him and causing him to flare constantly. Is any of this normal. Thank you everyone who offers advice in advance. Im eager to learn the proper ways to care for Betta in hopes he lives a nice long happy life.
