Keep it clean, and you can put neosporin (antibiotic ointment ) on it.
Also, please unplug the heat rock.
Keep an eye on the burn, if it looks to be infected, a vet visit is needed.
I'm sorry to hear about your hurt baby. Make sure you use Neosporin cream and NOT OINTMENT. Ointment holds in heat and does not absorb in as well. Switch to lighting as your source of heat. It is much more easy to regulate and is a more constant and reliable source of heat.
I just set Swordtail's timer for his bath and paused it so I could actually fill his soaking bowl up and he crawled over my phone and canceled the timer
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
