My poor pacman (after seeing pictures below, you will understand why he has this name) is ill.
on his head, he has a few spots that seem to be getting bigger.
the largest is about 2mm in diameter and 2mm tall.
the other two are still quite small but look the same as the largest one did about a week ago.
im sorry if these pictures arnt the best quality, but both pacman and ms pacman get very excited when someone goes near the tank (they expect food :D) so yes, he is still eating.
this picture doesnt give great scope on their size, but does on colour etc.
and this gives a bit better scope on how far they stick up.
these spots seem white underneath the scales... the scales look like they have been pushed upwards from underneath.
he has recently been treated sucsesfuly for fungus at the base of his tail. before he was treated for that, he floated when he was 'asleep'. after he got better he became just like any other normal fish and i was so relived, but now he has these, he has started floating again, even when awake you can see its takeing effort for him to stay down in he tank.
he shares the tank with his wife (ms. Pacman) who hasn't got anything wrong with her (and never had).
they are small fat fish (young), iv been told they are 'Ranchu' but i don't know if that's true. im not sure what their tank size is, but i'm pretty sure that its not too big and not too small. they have weekly partial water changes (usually 1/3 sometimes 1/2 depending on how messy they make it). the water is filtered and aerated by the water filter. they have live plants and are fed with a sinking food (so they don't get swim bladder). the food was suggested to us when we bought the fish and they have had it since (with the occasional treat of live food... ew)
i really want him to get better so ill be active on the forum regularly so dont hesitate to ask a question as i should be able to get back to you quickish, im going to try to get some better pictures but it may have to wait until he 'falls asleep'
