Good sentence! It is grammatically correct.
Corrected (less repetition): The tiny seahorse hooks its tail on seaweed and sips its dinner with its snout.
Why it is correct:
- The seahorse is one animal, so we use 'hooks' and 'sips' (singular verbs).
- 'Its' shows the tail and snout belong to the seahorse.
- All words are in the same tense (present), and the sentence ends with a period.
