Is there a community for asking questions about pet symptoms? Maybe a place where vets share advice?

I already go to my local vet with our dogs when needed but we have no vets for aquatic animals here and I could use some advice about an issue some of my fish have.

I could imagine though that it could also be a good place to share experiences and advice about more obscure issues for any pet, like SLO in dogs. We got a diagnosis from the vet, but a lot more advice online about it.
