anacharis can be planted in the substrate or left floating. Its up to you. How long are each stem? If they are 6", then you can split it in half. This way you have more growing.
I don't have any experience with liquid fertilizers, but I have used dry fertilizers. Dry fertilizers are much easier to deal with in my opinion.
