ok, listen, and listen closely, I have had a bicolor psuedochromis for about 4 months, it was my first fish, and is now in a five gallon by himself because i haven't the heart to get rid of him even though he was the terror of my tank. Anyway, i had a lawnmower blennie, had being the operative word, who starved to death because whenever he came out to graze, the BP would scare him back to his hole.
I had to take back a cinnamon clown, (note that a cinnamon clown is about 3 times the size of the BP) because I didn't have the five to put the bicolor psuedochromis in, the cinnamon had chunks out of all of his fins.
My sixline wrasse is missing a fin and has chunks out of his tail from one day of being with the BP. Thats when i had enough, the BP is now in quaranteen and I am getting another hospital tank this weekend.
the BP is a murderous monster, who as soon as he gets used to your tank, will begin a reign of terror.
To conrol pods, i suggest a sixline wrasse, I've had mine with a false perk for a few weeks so far and there have been no problems thus far.
HTH
BTW, sixline wrasses eat more pods anyway, they spend all of their waking hours foraging the rocks for pods.
