poor sam

Started tetracycline treatment. Asking advice on a particular betta forum. His cloudy eye is improving, a bit more alert and active, but the lump under fin is even worse. Like white stuff bulging out now. Looks like lymphocystis? He sleeps either in one lower corner under the heater or behind this chunk of wood and plants-

where I also tucked his almond leaves. It's kind of cute, he has a little cave back there under the driftwood ledge.

from this angle you can see how his good side really is smooth-scaled, and the kink in his tail is pretty visible here.
