hey not sure if i am over reacting, but only newish to fish keping realy and have recenty got some mono's, to me they look like they should be starting to get color and seem a little dull, they are aroun1.5 to 2 inchs big, i can only get them to eat bloodworm, they will not eat pellets or anything else, i am not sure if it is their diet or not thats making them lack color, any recomendation on what i should do or if there is anything i am doing wrong, the water sits on 27.5 degrees everyday and the ph levals are great,
