Sometimes watching too many videos and reading too many posts, can make you doubt decisions you have made. I thought i was doing a good thing, but purchasing a 3.5 gallon tank for my Sushi and now I'm wondering if it's too tall. I read something and saw a video about "tall" not being good for Betta Splendens. I do have a floating log and some silk leaves for him to lie in, but I'm needing some opinions or reassurance on my aquarium. It's 3.5 gallon, with heater and airstone/sponge filter, some glass marbles on the bottom of the tank and its roughly 12-13 inches deep.
Thanks in advance!
