hello i have a small 5 gallon freshwater tank.In it i HAD one goldfish(had him from the start)one betta(had him from the start)and a snail.A week ago i won a goldfish ar the chatham fair(prolly a very cheep feederfish)and i introduced him into my peacefull tank.Thats when the fish masacare began!I observed dirt(the fish i won)for the first few days just to see if he was healthy and he looked great!He was smimming eating and looking healthy i properly aclamated him and i thought it was the begining of a great new life for dirt.But i woke up one day and feed them and at first i dident notice anything out of the ordenary except it looked like something took a chunk out of dirt!I figured it was just my betta being a jurk and i reely did not care so i took dirt out of the tank and that was the end of that.(so i thought)I considered the posobility of a peracite of some kind or a illness(ick)but i decided it happened to quickly .After dirt died i closely monitored my fish and they looked great.two days after tht i woke up one day only to find my betta riped to shreads!I found him floating upside down a chunk was missing from his head and all his fins were ripped off
I started brainstorming what could have caused such a thing.My fillter?-no he couldent fitt in it and eaven if he could i prolly would have found him in there not the main tank.Kitty?Kitty has no front claws and the opening in the back of the tank is not big enuff for here to stick here head in+she would have eat the fish not just leave it in the tank.so what could have done it?Chunk(my goldfish)he is very fat maybe he got up for a midnight snack he has been acting weird sence dirt was introduced? Sneily?(my snail)he is a herbavore.So what did this to my fish?I know it is my fault i should have taken the necacary steps after dirt had died.(cleaning everything in the tank)My freind was there when it happened and he told his mom who once kept fish and she said it was ick. what do you guys think?
