Since i recently lost a Tire Track Eel (Mastacemelus Armatus), I'm deciding which one I should add to the tank, either a Rope Fish (Erpetoichthys calabaricus) or a Peppered Loach (Lepidocephalichthys guntea). I have a packed planted tank 75gal. What are the pros and cons of keeping each of those? Space is not a problem, I can always move them to a 150gal if they grow too big. Thanks
