A few months ago, one of my otos got stuck behind the filter. He ended up being back there without me noticing for about 2 days, but he survived!
I figure he found some tasty algae back there, but ventured too far and got stuck.
A couple days ago, I posted about one of my white cloud minnows getting stuck behind the filter. Ok, no idea how he got back there, but he too made a speedy recovery.
It happened again, and this time was a bit more scary. I was doing a water change, and as I pulled the gravel vac out, I accidentally bumped it against the glass, which freaked out my betta, Enigma. He darted to his favourite hiding place by the filter intake. I set the vac down, and went to peek to make sure Enigma was ok, and WTF he's behind the filter! Upside down! Took a quick pic, and set about puzzling how to get him out safely, since the suction cups on the filter stick like mad. I was able to pull the bottom out a bit, and he was able to wriggle himself free.
The filter is a Stingray 15, which I'm quite happy with filter wise. But clearly I need to block off the filter so nothing can get behind it. I was thinking maybe just cut a sponge to size and put it behind the filter. But would the sponge get scummy quickly?
Any other ideas?
