Had this single bangaii cardinal for about 2 years since our tank was new. Came back from a weekend vacation this week and noticed he wasn’t eating. Today I looked a little closer and found this in his mouth. It looks like some sort of spider/crab or shrimp carcass. Not really sure what to do with him. Photos aren’t the best as it has been kinda hiding since we noticed this.
Appreciate any help
