I have a 75 gallon with a fluval fx5 filter on it with 3 red bellies that I have owned for about 10 years. All my other tanks have been converted to the rimless look except this one. I really want to change this tanks to a 120p size tank (18x18x48), but I am worried about fish jump. I have never heard one of my fish hit the lid in the past, but they sure splash like crazy at feeding (pellets - no live feeding) and if I lost one at this point it would be super tragic. They are nice and big, get along well - not to mention a full size red belly on the floor trying to bit anything that gets close with my 3 little kids in the house.
I was thinking I could do one of those screen lids, but I would have to come up with a way to weigh/clamp it down that does not look like crap. Or there is the option of making all glass lids with the back corners cut off to allow the filter to ingress and egress.... but i have done that in the past and they stay foggy and grow algae really fast.
Has anyone else gone rimless in the piranha game? have any suggestions?
