I have a 7-8 inch Clown Loach I've had for 30 plus years and she seems to be egg bound. The tank is a 110 tropical that also has 2 male Clown Loaches that I've had that long. The female has gotten huge in her abdomen and the males are brushing against her ( not aggressive). I've taken pictures of her backside and when you zoom in it looks like eggs under the skin and I've seen her drop and egg. How can I help her progress? I've done small water changes I put fresh carbon in, I put Erythromycin in and I also add salt anything Else????
