Back with some more FAQs sent to our Marine Bio staff.
I’m raising a baby silver Arowana. I would like to know, what meds do you recommend to keep in stock, How effective are vitamins, and are any water treatments needed besides prime or salt ? What is black water?
Marine Bio answered:
Some Meds I recommend keeping on hand are Kanaplex, Sulfathiazole, and Quick Cure.
These products treat a wide spectrum of diseases and are all very effective. Beyond all things, water quality and temperature stability will be the most important things for your arowana. Vitamins are completely subjective. Some people use them. I personally do not. A good food will have everything he needs to stay healthy. Try to get him off of live food as soon as possible. When they are small, floating pellets work pretty well. Just make sure to get small ones.
Black water is the term for the coloration and conditions found in parts of the Amazon River. There are natural organics, acids and tannins that leach into the water from wood and soil to create very soft water that is colored almost like a dark tea. There are several products that can simulate these conditions for you if you prefer.
I currently have a 30 gallon bow-front salt water tank with one Condylactis Anenome, some Mexican turbo snails, live rock and blue legged hermit crabs. I wanted to transfer everything into a 75 gallon tank. But I just lost all of my fish to ich. Should I use new crushed coral, or use the old stuff from my little tank? What would be the safest way to know I won’t get ich again? I will set up a hospital tank, but I don’t want to have the same problem in my 75 gallon.
Marine Bio Responded:
Since you have recently had ich in your 30 gallon tank, there can always be the chance for another ich outbreak since the encapsulated cysts can hang around in your tank for several weeks. If you transfer the sand from your 30 gallon to your 75 gallon, you increase the chance of having another outbreak. If you start with new sand, and add a new fish without quarantining them, you still have a risk of getting ich in that tank as well. If it has been over a month since you have had fish in your tank, I would probably go ahead and add the sand from your 30 gallon tank just because of the good bacteria that is thriving in it. It is up to you if you want to buy brand new sand and start over, or use what you have and add new to it. There are pros and cons both ways. Ich is very tricky, the best thing you can do is quarantine and keep the conditions in the tank pristine. Poor water conditions and stress may prompt an ich outbreak too. You may want to keep meds on hand in case of any problem, just be sure you’re using a reef safe medication or remove your inverts to treat in the event of a recurrence.
