my oldest was a jack dempsey. when i got him i had an empty tank running. a friend brought him from 2 streets over on a bike in a net and dumped him in my 30 gallon tank! even though i thought i "knew it all" about fish i was really ignorant in fish keeping. years later (thanks to the wonderful internet) i had done lots of research and tried to give HER a better life. i realize now that im lucky she survived the 12 years of constant moving, no heater, no water changes, and no de-chlor! here is the pics of jack renamed misses jack r.i.p.
