I just got home from school to find my betta horribly mutilated! He was just fine when I left in the morning. I have a 16 gallon tank thats been up n running since May. I currently have 2 male guppies, 1 female guppy, a male red platy, a female Mouse platy, and a baby brittleno s r pleco. Could any of them have done this?
Also, i recently euthanized a female guppy because i believed she had a callumus worm (nematodes) n her spine was bent. I currently have one more male guppy whos been bloated up like a balloon for a few days. Hes quarantined in my hospital tank because i fear he could have a parasite too. However, no other fish are exhibiting symptoms.
I removed poor Sir Fishsalot (the betta) and for now hes in the little plastic cup i got him in last summer.
What happened to him? Is he gonna be ok? Please help me!
