Hello everybody, so in my high school we have an oceanography class for the juniors and seniors (I'm a sophomore). They have around 6 tanks, 5 fresh 1 salt. They are around 50 gal a piece. Long story short the saltwater tank needed a good scrubbing and I am more than happy to clean her tanks! Brown algae, green slime algae, red algae. It only has 2 fish a green clown goby and this thin eel looking fish that is black with white spots? The teacher said they are both gobies but I am so puzzled as to what the black little fish is? I will get a picture tomorrow I'm sure that would really help! Thanks
Angela
