Pink tail Chalceus are an awesome addition to your large fish tank! They grow to be about 12 and are known to be shy when not given hiding spaces. They can be paired well with semi aggressive fish such as geophageus, leporinus or catfish. Despite being shy, Pink tail Chalceus are territorial and need to be given plenty of space. They should be kept with fish that are about their size since all fish that can fit in their mouth will be eaten
