They help a serious raykeeper keep thier sanity..... If it wasn't for these guys I'd probobly be out of the hobby.
I get frustrated with all the work rays are..... All the waterchanges, breaking them of certain foods, fighting, waterchanges, meds, eating my other fish, waterchanges, set up more tanks for pups, waterchanges. After all that work sometimes I don't even wanna see another ray for a week.
The eels put on a great show when fed... EVERY time. I clean that tank once a month.... Best part... They hardly EVER DIE. I've lost less eels in my life then I have rays this year. VERY tough, LOW maintainance animals. Always visible from somewhere in the tank.
I find extreme peace and tranquility in Morays. They all get along... They are almost bulletproof.... I had Ich wipe out my entire collection of SW fish.... The whole time the fish were dying NOT one eel even so much as lost its appetite..... Morays are the bomb no matter what way you look at it.
