So far i've been keeping fresh water fish for 19 years, since i was 11 years old. Last year I got my first spiney and had him for about 6 months. He was by far my favorite fish species. I left the top open for 2 minutes while I was doing some work on the tank, and while it was open he jumped out...i picked him up and put him back in right after he jumped out but he still died. I was given another tank by a friend who was giving up on the hobby and decided to get another one. I think my favorite thing about them is watching the way they hunt for food and explore; and when they feel your vibrations they always poke their heads out to see whats up :]. Anyhow. nice fish for sure, thanks for your advice.
