Help with my Molly fish
I have two questions if anyone can help. 1) I have a 5 gallon aquarium with 2 fish. One is a Black Molly and the other is a Silver/White Molly. I've had my black Molly for over 2 weeks now and just added the Silver Molly about 4 days ago. The Silve Molly is quite bigger than the black one and I have noticed that it dominates the tank. When I feed them the white molly vacuums up all the food before the black one gets to eat anything or the food has already fallen to the bottom of the tank. Should I be concerned that my black fish isn't getting any food at all? I have noticed the Black Molly spits out the little bit of food it does get and then just swims away. I feel sorry for him. Could it be sick? I've also watched the Silver Molly spit out the food but it eats it again right away.
2) This may sound silly but can fish diseases/parasites be transfered to a person? i.e putting your hands in the water/changing the water in the tank? Thanks a bunch! :)
