Its about 2 years old and about 5 inches long now, but the only thing it has been fed is driftwood and likely the occasional leftovers on the bottom of the tank. Its growth is great and colors are good, but i have been wanting to feed it a more varied diet. I have tried zucchini and left it in the tank for 3 days, wouldn't touch it. Was going to try some cucumbers next, but i did notice the other day that its taken an interest in the shrimp pellets I feed my cory cats. What would you all suggest? This royal is my favorite of all my fish and I want it to get more in its diet.
