Size is between 3.5ft & 1.5ft all were caught by me. Paramus from where they were caught in charneys thread. I have coral in the tank coz our water is super soft. Fish with them are Kuhlia marginata and rupestris (jungle perch and red tail jungle perch). Both occur alongside the eels in the wild. Temp tank while my partner and I do a major reshuffle of our fish.
