Mixed reviews on fit and durability; may not be suitable for all dogs.
Based on the reviews available at present this product will not be universal for the fish and the results may differ.
Recommended for maroon clownfish for its color enhancement and health benefits
Some fish species nearly avoid it entirely
"seems to be very well received by my large Passer and a few anthias if broken up. Fish color and health seems to be great."
"I have 150 gallon Marine tank with 38 fish in it they won't touch it I had to scoop it out with a net"
Correctly the product will appeal to some breed of the fish based on the preference the fish have.
