i was wondering if i can put a freswater eel in my 90gallon frontosa tank? if you look in my gallery u can see the size of my frontosas. i was wondering if the eel will eat or try to eat my fish.
I would maybe try a rubber eel i think they are called strange looking live bearers that make very interesting pets. I am not sure on the aggressiveness of fronts because I have never had them but they may nip at the eel
The rubber eel aka the Caecilian worm (Typhlonectes natans) is actually an amphibian. These critters prefer soft water so, they would make bad tankmates for hard-water fronts. They're also not opposed to biting any fish they happen to run in to. Rubber eels also have a habit of shedding their entire skin in long threads that can easily block filter intakes.
What sort of eel were you interested in keeping with your fronts? Spiny eels could work. The main problem is that the food for eels (worms for the most part) can cause intestinal problems in your fronts.
Actually the Monopterus albus (rice paddy/asian swamp eel) would be just about perfect. they will easily adapt to the water conditions, live for decades, and get big enough not to be eaten while not eating the fronts (40" max). They also will eat any meaty food including pellets. You would have to start with one not more than 2 1/2-3 times as long as the fronts.
But if you like the slender and long body, you can also go with a reedfish. For some reason, I could just watch my reedfish, Alan, for hours. I don't even know why. Also called a rope fish and snakefish.
