Questions.,.,
1.What type of plant does a ghost fish eat?
2. What type of Fish eats a ghost shrimp?Be specific
3.what the habitat of a ghost shrimp?

Tnx in advance

1. The only plant I can think of that they eat is plankton..otherwise they prefer aquatic insect larvae, bacteria, fungi, mites, and small invertebrates.

2. Lots of fish eat ghost shrimp. An angel fish for example.

3,They live in small holes in a freshwater environment.

I hope that was somewhat helpful.
