I have a 220 gallon tank with a nice pack of 12 clowns between 4-6 inches. Some I’ve had for 8-9 years, others slowly added when I see bigger ones in a local store..... I have noticed that I see loaches in stores etc, and their colors much more vibrant, with red fins and tails. Mine seem to be “washed out” with dull fins... I purchased a few maybe two months ago and they were initially beautiful, but also have lost their red fins. They are all fat fish, just not colorful. Tank parameters fine, Denison barbs and two catfish are tankmates, fed daily frozen bloodworms, flakes....what am I doing wrong??
