Spike, according to a book "The Springs Of Florida" from Doug Stamm... the fish I am referring to are called 'Redeye Chubs'. I may be ignorant and just not know that they are a type of Cichlid.. so please let me know if they are

Looking at the site posted above... they are listed as: BLUEFIN KILLIFISH (LUCANIA GOODEI) Not all of them have the bright coloration and are just bland ... but they look the same otherwise. And yes, to answer the question I did collect them myself. They're difficult to get them to eat.. but they seem to love freezed dried tubiflex worms and bloodworms.
The one other inhabitant that I've neglected to mention is a "Loggerhead Musk Turtle" that I nursed back to health. I caught him when he was only about an inch long (from front to back of his shell) and he had a fishing hook stuck in his claw. Now, you can't tell it was ever there and he's getting to be close to 4" long. According to the book listed above, he's part of a "subspecies almost endemic to Florida Springs. These negatively buoyant turtles roam spring bottoms, never having to reach the surface for air. Their ability to absorb oxygen through their skin finds them occasionally in underwater caves where no other turtle would normally venture... Loggerheads reach a maximum size of only 5 inches". Very intelligent creature... and will even let you hand feed him (just watch your fingers

) He's gotten the nickname of Jaws because he'll chase your finger around through the glass trying to 'sample' it
Edit: Yes, I looked at the sunfish on your site... closest they come is the American Flag one... but they dont have that coloration, just a dark spot in the middle, similar to that one. And to clarify.. the turtle (jaws) has his own 25g Long in the living room.. he's a family pet.
