Chris,
No openings at all! That's great....I use the egg crate. Is the gutter guard easy to remove to get into the tank if needed?
I have a snowflake that I have had for many years--since he was the size of a large engineer goby! He is now between 2 and 2.5 feet long. I feed him frozen shrimp most of the time-never live food.
He has found his way out of his tank twice over the years--once the cat found him (and thankfully did not know what to do with him), and the second time he was temporarily moved into a small tank . He did not like it, so he found a small opening and slithered into the cichlid tank next door--which totally freaked out the cichlid!
I would like to eliminate a tank and therefore find a good home for him. I do not want to take him to a LFS as all their tanks are uncovered and who knows if the buyer will cover their tank either. If you are collecting eels he is your if you want....I know you will give him a good home...
