The tank that I thought was a 2.5 is really only a 1.5

Yeah I thought about putting them both in the 5 gallon but I just couldn't do that to Kaiba. He's gotten so used to having so much room and unlike Yu-gi he actually uses it and is on the move a lot. My friends and I go to the petsmart often so I'll be able to keep an eye on him to see when he gets adopted. And if (even though I hope it doesnt happen) one of my friends bettas die or *tear* Kaiba dies and he's still there I'm sure we'll snatch him back up again.
