Just bought 2 really pretty red tuxedo guppies for my daughter's 10 gallon yesterday. Woke up this morning and they weren't anywhere to be found... until we looked on the floor. They jumped out the small opening where the HOB filter spills the water back into the aquarium. Are guppies known to be jumpers? What is the best type of material to cover any openings?
