Hithere I'm currently stressing out as I believe my young albino polypterus palmas may have ingested a small piece of gravel as she has a abnormal lump on her right flank that has a dark patch around it. I really don't want her to die she is an amazingly beautiful fish. I know that one of four things can happen if she has she'll either regeretate it or it'll find a place in her stomach where it can hurt her until she's big enough to pass it or she'll pass it or it'll cause an impaction and she'll die which I really don't want to happen she's had it for at least two days now as I noticed it last night. What should I do and is it actually gravel or is it just a lump of good as it appears to have decreased slightly over the course of today.
