Is there any great gravel i can use for live plants? A great gravel that fish will enjoy?
I hadn't heard that yet... what type of fish eat sand that ought not to?...some fish will mistake the sand for food and eat it, which will give them indigestion. ...
Interested in hearing about the specific species that have been effected as well...... Yes, some fish will pick sand up in their mouths and filter through it, blowing it out through the gills, etc, but I am not aware of any cases of "sand colic" (sorry, thinking in equine terms at this point) in fish.I hadn't heard that yet... what type of fish eat sand that ought not to?
I would say that sand is a great default substrate, cheap, works for most fish and works great for plants.
"Choking" can only occur if the water flow is cut off to the mouth, as the gills are located in front of the throat. An obstruction in the throat leads to starvation, not suffocation.
The plastic plant must have had food stuck to it ;-)
