Answer
Water lilies need a lot of care and they prefer a tall, column aquarium. water lilies are nutrient needers, they need plant specific soil, higher lighting, and often times root tabs if they are not doing well.

I'd just advise you on getting a larger tank or rehoming some of those fish. Most of those fish get way too large for that tank.
