OOOh a dung beetle? Ed feel free to name a few to make me feel thick
You know what I mean though, what in the aquarium eats poo? Nope, nope, you'll just have to pull your finger out and clean it yourself. I was once very sarcastic about that to a customer, with a smile on my face so they couldn't get too cross
Between that and when they say (insert terrible thing here like 5 goldies in a 20 litre tank) "but the fish are perfectly fine". My reply? "Well unfortunately it's not like the fish go round with smiles on their faces to let us know but I can assure you they are not". Hehehehehehe
