I'm going to look at a 135 gallon tank tomorrow, its at a great price $550 for tank stand and accessories. It's a deal I can't pass up. Anyways, I would really like to get a fire eel and was wondering if this would be big enough? I've tried researching but I get such mixed results. And if it is big enough, is there room for any other types of fish? Any suggestions if so? or should I keep him by himself? the dimensions of the tank are 72"L-18"W-24"H and I plan to use sand (I've only ever used gravel, any advice?) and I plan to try planting it, though I know there is a chance of them being uprooted. So far I know that they are escape artists, I know I may have to get a more stable top for it. I know they like to dig and bury themselves and that it should be the first to get established in the tank. Any other tips? it is so hard to research online, you get so much info contradicts itself. Any info or tips would be great, Thanks ^_^
