LMAO!!!!!
Sorry.... so my friend just got a nano biocube. holds about 8 gallons of water.
Long story short she has a very serious hair algae bloom. No big deal I tell her. We moved the tank etc etc...
So she can't handle waiting to throw something in. She goes local to buy a cuc (o.k.) and comes home with a fish the "guy"

said would fix it.
I look it up and it's a Harlequin Bass (Serranus tigrinus)
or a Spotted Hawkfish (Cirrhitichthys aprinus)
