My tank (a U.S. 20 gallon glass fish tank) has been setup and running since the end of September of this year. It has several African Dwarf Frogs, a few Dalmatian Mollies, a bunch of Molly fry in a temporary breeding net, some Cory Catfish, and one Plecostomus. Originally it was meant to be just an African Dwarf Frog tank, but when I was out of the house I returned to find that the tank had become home to a pair mollies…which produced some fry (evidently my family thought the tank was boring without fish).
Exactly one week ago today, I tested the water via some water test strips and found that the ammonia and nitrite levels were zero while the nitrate level was normal (under 20). The water temperature is kept at 78 degrees Fahrenheit, and my filter is a Marineland Biowheel 200 rated for up to 55 gallons. After testing the water, I did my weekly water change, and then left to visit some friends. While away, my family feeds the fish /frogs, and looks after them.
I returned a few days ago, and today just noticed that one Molly has white “salt” looking spots on all of its fins. I fear this may be ick, and am fearful for all the little souls in the tank. Unfortunately, I ran out of the water test strips, so I cannot give you a current water level count. Furthermore, I have no hospital tank, and thus must treat the whole tank. However, from my understanding, one must treat their entire tank for ick anyway. Before posting this I went ahead and did my weekly water change…
In short, what medication would be best to use to help get rid of the ick, and not harm the African Dwarf Frogs, Plecostomus, the Cory Catfish, the Dalmatian Mollies and their fry? I really have no clue, and am therefore hoping I can find some advice here. My greatest fear is following the pet store’s advice, and inadvertently harming my frogs or any other of the above listed fish (I read that some fish medication is poisonous to these frogs). Since I do not know much in this regard…..please help…I want to do the best that I can for all of those in my care.
P.S. Sorry for the long post, but I figure that it is best to give as much information that one can in this situation. Thank you for your time, and have a nice day.
