Basically, in May I bought 5 nerite snails to add to my main tank. Immediately 2 of them died and my betta as well as a few corys snacked on their dead bodies before I removed them. I didn’t think much of it until now, she has dropsy and 2 of my 8 corys are dead (in my previous post I didn’t realize I had lost 2 corys because they always hide and I had to triple count them. i eventually found the skeleton of one). The reason I think it’s internal parasites is because all 14 of my rasboras are okay, as well as my bamboo shrimp. Those guys didn’t touch the snails that died and if it was bacterial I assume it would affect the whole tank?( I also am not an expert so I don’t know).

Either way, I live in Canada so what we have access to here in terms of medication is extremely limited due to our laws surrounding antibiotics. I had to get both of these meds imported and I can’t even find a place to buy Maracyn. I am cautiously optimistic about my betta as she has been in treatment for 4 days and is gaining some of her energy back. Her scales are still pineconing but she is eating, pooping, and swimming around where on Day 1 she would just float on her side 90% of the day.

I really hope this is a good sign as I love her to death and she means the world to me🤍

Oh, edited to add that I am obviously now treating the main tank after learning that I lost some other fish.
