I saw a picture of an arowana which looked like it had a mane around its head, and the main looked like bubbled skin. Was this a doctored photo or are there some species like that? The lady at the fish store told me shes never head of one like that. Also, this store was selling blue arowanas and they only had two that were about a ft long or more. They were each $500. Are they overcharging or is this a rare fish? Someone who worked there told me they dont ship blue aros anymore.
