Bamboo Shark injury help
I have a 4 year old bamboo shark that developed or received a deep wound on his nose, about 3 weeks ago. It normarlly lives in a 700 gallon aq with two other bamboo sharks and two large horseshoe crabs. I suspect that the wound is from the pump intake - screen was off for one day, but it could have been caused by the horseshoe crabs too, but they have lived together for over a year without any problems. I moved the shark into a hospital tank - 50 gallons with a wet/dry sump and protein skimmer - and have been treating the tank with 10 ml of Melafix a day, and the wound is shrinking, but not very fast. The two pictures were taken four days apart and shrinkage of the red area can be seen. The shark is eating and reacts when someone is near by, so that is good. I am wondering if I should just continue with the treatment or switch to something else. Someone suggested Baytril, but I am nervous about switching with out some advice.
