ok got a question for you guys,does the headgrowth on oranda goldfish bruise really easy? If my fish swims into driftwood, hits his head, etc, it gets red and looks like a bruise but goes away over time. Today i came in and he has a red spot on his head, looks like a large broken blood vessel. This has got me worried that it may be a bacterial or fungal infection of some sort. What do you guys think?
