Overnight one of my ADFs wedged himself between the glass and my CO2 bubble rack. He drowned. Aside from being tortured by images of a struggling frog trying to surface, I'm pretty angry.
Is there any aquarium safe underwater tape or some kind of barrier I can put along my CO2 rack to prevent this?
Is it one of those like, CO2 ladder-bubble counters?
Worst case I'm wondering is there anyway to make it so it isn't so close to the glass in the back, more space in front and behind it? Or to put some other decoration you can find behind it?
A buddy of mine had fish get behind the rack more than once. What she did was get a piece of PVC pipe a little wider than the ladder, and put caps on both ends. She then cut a slit in the length that allowed the ladder's bottom edge to sit into the PVC pipe and siliconed it into place.
The end result was that she could put it anywhere by just burying the PVC pipe in the gravel. She'd put it behind large leaf plants or rocks so you couldn't see it.
