I picked up a ram chiclid 3-4 months ago. They had the fish labeled as a German Blue Ram. However it's not coloring up and I'm not sure if this is because of bad breeding or if it might be either a Bolivian ram or gold ram instead. He does have a black spike on his front dorsal fin, although the pictures don't show it. Also, not sure if its a male or female. Anyways the fish is doing great, very active and eats well. Always comes up to the tank and interacts with me. Sorry about the photos, he moves so much it's hard to get an in-focus close up. My other question is on diatoms. Had the tank around 10 months and still having horrible diatom algae issues. It takes down all my live plants, covers the leaves, and my tank walls. water changes once per week, water levels all look good, I try not to overfeed. Tank kept at 81/82. Good water flow. Plants do grow but eventually are covered in diatoms. Would love to know what I can do to fix this so I can get a lush green look to my tank. Thanks guys!
