Hi all, I went to the lfs looking for a normal bristlenose pleco, but was offered a 'red bnp' by the person working there. It has these little black marks on it so I'm unsure if it's calico markings or if there's something wrong with it? Picked up a week ago, water parameters are fine and it is eating and active. It is only around 4cm long or so. Picture below. There is a large black mark on the tail fin, a smaller one on the dorsal fin, and some little black speckles elsewhere.
