Hannah Parker Posted May 24, 2022 Share Posted May 24, 2022 Hi everyone, I've got a sad and frustrating problem on my hands. The short story is I had a pair of yoyo loaches in my tropical community tanks for over 4 years, and this tank has been running in perfect balance and harmony for over a year. I have a giant male plakat betta, various platies and guppies, synodontis petricola catfish and a few mismatched species that were combined from old community tanks and their schools not replaced (I'm trying to let them die out naturally) such as chili rasboras, hasbrosas pygmy corydoras, and a salt and pepper cory, and of course now only 1 yoyo loach. You can check out the thread here for context on how I got the 2 yoyos and lost the 1, and you can check out my thread here for context on my dilemma with my remaining yoyo loach. Moving on to last night, during feeding I noticed my betta's face seemed swollen, and upon further investigation I discovered that the left side of his face had been injured, with a couple of red open wounds and the scales on that side of his face pineconing. I was shocked and so scared, because this tank has been in perfect harmony and everyone has always gotten along. I treated the tank with Melafix, Fritz Indian Almond Leaf extract, and aquarium salt. I then put my betta in a net near the surface of the water in the tank and that was held in place by the lid overnight. I had treated a bad case of dropsy like this before and forcing the betta to rest in the net worked wonders. I fed him fluval bug bites and he ate normally. He was also acting normally so I am hoping he pulls through. I also wanted to put him in the net to protect him possibly from the culprit. Here are the videos I took of the injuries: I'm 99% sure that it was my remaining yoyo loach that did it, I can't think of any other fish in there that would. I have barely seen my loach since his counterpart died (he's hiding a lot), and his behavior is now very different. I believe that he is upset at being the only loach now, and has either turned semi-aggressive or was trying to interact with my betta because he is now lonely, and got too enthusiastic and ended up hurting him. I am really worried about my community tank, and have committed myself to this loach and really don't want to get rid of him. The only thing that has changed in this tank is that my other yoyo died and now there is only 1. I will be moving my betta to a spare 5 gallon if he takes a turn for the worse or is injured further. Does anyone agree with my hunch that he is upset at being the only loach? Do you think adding more loaches would restore balance? I was really leaning towards dwarf chain loaches because I can get more for the size of my tank, but am also open to 2 more yoyos or 2 zebra loaches. Thank you all for any input. 2 Link to comment Share on other sites More sharing options...
