I have had this eel for 9 years when he was a small baby and never have had any issues with it touching any of my fish. Have had him in my coral tank and does well with cleaner shrimp which he allows to crawl in his mouth to clean. Must sell him though do to moving for a new job. Would like to get $150 for him. Willing and able to take credit card or paypal for payment. Please text me at 858-997-4164 can send pics. Must sell by the end of the week as I am moving cross country.
