Well I recently got 2 White Cloud Mountian Minnows to add to my 5 gallon tank with my Betta. When I got home from school today I found the female White Cloud died because it got stuck to the filter intake . I have no idea how that could be because the food flakes swim right past it and never even look like they get any closer when they pass it... Anyways I have 1 male now and I plan to get 3 more and I was woundering would it be a good idea to get 3 Albino Cory cats to go in the tank also.
