leopard danio

[northpaul]

hi everybody i have a leopard danio that has a strange lump underneath and a red blotch on one side still eats but dont seem as active any help welcome

 

[The-Wolf]

there are many causes for lumps and bumps and for red blotches
Can you list all symptoms, even if it seems insignificant to you.
what are your water parameters?

In the meantime, you can give the fish a salt bath and do a 30% water change in the tank.
