I have 4 jewel cichlids in a 75 gallon with a tt eel im growing out. How can i get the jewels to red up. They range from smallest about 1.5 an largest being almost 3 inches. Ive had them in the past but have never had an issue with them getting red. They are very active any growing nicely. Just cant seem to get the color to show. Im positive I have 1 male an 1 female not sure about the other 2. Any suggestions
