So we've got another filter in there and treated twice for the white spot with WS3 and bought a little hospital tank that goes in the main tank just to separate the white platy that keeps getting picked on and now the orange platy is picking on the blue platy, it keeps pecking it. This is driving us crazy, the neons seem absolutely fine after being treated for white spot but we can never seem to keep the platys happy, if the orange one isn't pecking the white one, she's pecking the blue one and keeps pecking until they get weak, so now I've had to separate the orange one and put her in a sciv, what's going on, is it the after effects from the white spot again or what, how come the neons are ok with being so small but the platys aren't x
