EN fish are compatible with any slower moving community tank fish. EN can actually be sometimes territorial of their caves or aggressive when it comes to food but they can't do much damage. I have had my EN fish for almost 2 1/2 years now and he is doing great at about 9-10 inches. I provide him with two caves and he also likes to hide in this one piece of driftwood I have. They like shadowy planted aquariums with REAL PLANTS...you either have real plants or no plants. I feed him/her frozen bloodworms or frozen brine shrimp that have been melted and drained so as not to release extra phosphates. I have 55g planted aquarium..his/her tank mates include:
9 rummy nose tetra
5 mini yellow rainbows
3 boesmani rainbows
bristlenose pleco
ottos
amano shrimp & skunk shrimp
zebra snails
SAE
red tailed black shark
2 Pea Puffer fish
This is an amazing fish. Remember they are scaleless fish so every change you do cannot be too drastic. Use organic medications if you have to when it comes to ich but try just raising the temperature at first. They don't like a lot of salinity. He/she will be shy of your hand at first but soon he will start eating straight from your fingertips. It took me about 3 1/2 months so be patient.
