Whats the best "gravel" to use for fire eels? I'm currently using a fine gravel but my guy seems to have issues burying easily, and I'm afraid he's gonna cut himself up one of these days. I'm thinking either pool filter sand or Eco-complete as the 40 breeder he's in atm will be converted into a planted tank once he's out-grown it. Or Is it best to go bare bottom? What do you guys use/ recomend ? I'm also getting another pair of babies this week hopefully
to live with "cuddles" after loseing my other eel i feel bad as he/she seems to be almost lost without a buddy. And the needle nose gar fish just looks at him apprehensively. haha he's smaller then "cuddles" is now. past 1.5 monthes she's already grown a solid 2" so up to over 14" 

by the time i get it re-vamped cuddles is gonna outgrow the tank. also got a line on a 180
