The fish, 100%. I didnt have a choice, I was born into it. Grew up with large tanks all around the house. I also grew up on a farm and with relatives that had farms. Chicken farms, egg farms, cattle farms and horse farms. I always had cats and dogs and rabbits and hamsters and guinea pigs and chickens and pigs and horses, etc., at my houses. Like any kid who grows up in the country we were always hunting, fishing, playing in the yard looking for bugs, frogs, etc. I remember when I was 3 finding frog eggs and hatching them, then salamanders, etc. I remember when I was about 5 and I found a HUGE Spotted Salamander and I took an old 20 gallon fish tank in the barn and put leaves, moss, branches, etc., in it. Had him in there for a few days before he crawled out and back into the wild one night. I was devastated. Ive just always liked having animals around. I find the fish very relaxing to watch, and I only keep biotopes now, so its fun trying to make their tanks look like a place theyd actually live in the wild.
