ive done everything i swear.. i do it wen the lights are of and i think they are asleep.. i recon they smell the food.
i made the little cave even littler i put anything i could find in the way of the entrace.. i got desperate last night so i put in the lid bit of a coner box filter.. with the little hole in the top for the outlet tube? and tuesday managed to get in there eat half the wafer get stuck and then get out through the little hole!!!

people should never underestimate the power of a goldfish! houdinies!
