Thank you so much for helping me identify those fish I thought they were tetras so that’s why I couldn’t find out what they were. A lot of the fish looked skinny so I’ve been feeding them blood worms and died brine shrimp. A couple of the tetras do have growth on their mouths so I’ve been treating the whole tank with microbe-lift Artemiss. Here is a picture of some of the fish with growths I worry I may have to put some of the poor guys out of their misery.1st picture has 6 neon tetras and 3 white cloud mountain minnows.
2nd picture has 2 normal white cloud mountain minnows in the middle and a gold white cloud mountain minnow at the top.
3rd picture has a group of gold white cloud mountain minnows.
The fish are skinny and I'm hoping that's just lack of food before you got them. One of the neons in the 1st picture has a funny mouth, it looks a bit white on the top lip. Monitor this closely because it could be Columnaris and might need treating with anti-biotics.
Ok thanks I didn’t want to end up overpopulating my tank and risking the fishes healthAll the fish are egg layers. The females scatter the eggs and the males fertilise them. Then the fish in the tank eat them.
I wouldn't worry about having egg ripe females (egg layers don't get pregnant), just let nature take its course.
Ok thanks for letting me know not what I wanted to have to do obviously but i don’t want to risk the health of my other fish or let the ones that can’t eat suffer. Should I still continue a 7 day treatment in the tank just to make sure no other fish are sick?I would euthanise any that can't eat, however, you can see how they go after 24 hours of medication, but if they haven't improved after 24 hours, euthanise the ones with the gross mouths
Ok I’ll try that. Do you think that the other fish that don’t look sick need treatment? I just don’t want to risk one of the fish having the same thing and it just not showing yetNo. Don't euthanize the dying fish. Move them to another tank and concentrate medicine.
