Possible problem

[Cr7realmadrid]

2 things I got this watermelon royal pleco a while back and I've heard that if their stomach is not "full" basically consider them dead as it means they're not eating and for mine its stomach is kind of like that however he's always eating there's a couple pictures and second I was looking at my shubunkin and he's got these red spots on him and I bought him cause he was a bit red (he had red spots) but now he's got read in places I've never seen before if they're not something to worry about then its really cool however, I'm not sure
any help/ advice would be much appreciated

It could be red pest disease. I just did a little research but it seems easy to treat. I suggest you look more into it though, as I am not familiar with goldfish.

Unless an injury it’s likely an infection of some sort due to poor water quality/maintenance. No one will be able to give any advice if you don’t post any water parameter information.
