Myriophyllum pinnatum has leaves with significantly fewer segments, and plants of M. hippuroides tend to be very delicate in appearance. Both M. hippuroides and M. pinnatum produce elongate, strap-shaped to linear-lanceolate to spatulate leaves distally, either when they grow submersed and produce emergent flowering racemes or when they grow as Temperature & Water Conditions. As far as temperature goes, it does best in a temperature range from 72 degrees F-82 degrees F. If you want to keep your aquarium colder than that, Hornwort would be a similar and more cold-tolerant option. Myrio Foxtail prefers a pH range of 6.5-7.5.
