Interesting Behaviour

[Kyrielle]

So, I've gotten some peacock gudgeons (1 male, 2 females) and have recently run into a very odd problem. Oh the problem isn't that they won't eat. They're little pigs and will devour anything and even chase their tankmates away from their feeding area.

No, the problem is my male gudgeon seems to think the media box from my HOB filter is a massive cave that he simply must jump into. I suspect this is all part of his plan to impress the females by showing them how precisely he can jump into his new lofty bachelor pad. It bothers me that he does this as I don't think he can get back out and I think it's very dangerous for him to be jumping into the filter media area in the first place.

For the time being, I've placed a relatively fine plastic mesh over the outflow on the filter, but I'm looking for a less unsightly solution. I need something that will block him from jumping in, but allow the water to flow out, and look decent or at least like there isn't trash stuck on the filter. Anything that will fit more snugly will work.

Suggestions?

You should get one of those invisible fences and he can wear a collar and when he trys to jump out it'll give him a little shock lol. But seriously that is the only idea i have, maybe some small piece of glass or something you can replace the plastic film with?
