I picked up a snowflake eel yesterday, and sadly he managed to escape through a 2 inch gap at the back of my tank. I have a glass canopy and I have an over sized filter for my tank. My levels aren't the problem I believe it was just the stress of moving (They had just gotten him in the shop that day and I brought him home an hour later, he was still floating there in the bag) that drove it to look for escape. Sealing the tank all the way is going to be difficult, so I was thinking if I built some 'walls ' out of plexiglass to make the uncovered edges of the tank 3" higher or so. Would that help or would I be better off just trying to make small caps to completely seal the aquarium.
What do you guys use for eel proof aquarium covers?
