Can someone please tell me what kind of fish this is? It eats everything, it has helped with my pest snails which is great, but it eats the pellets I put in for my shrimp plus it's own tropical fish food,it has not bothered any other fish. I have a 10 gallon tank, water temp 79 degrees. My husband brought it home but forgot what it Was! Thank you, hope someone knows what it is It is all white, no other markings.
