so I should just round them up and take em back to petsmart? So ar its just the two in the photo that show signs of it, my tetras seem ti be okay but yeah I'm really bummed right now >.<
If you have ich in one fish ... you have it in ALL, spots or no spot.
Generally, a cycling tank is very stressful to fish & bring on all sorts of illnesses. Phone & see if the lfs will take the fish back, but Petsmart likely will not, esp. with ich. <My local PS will however, give you free meds to treat them ....>
Ideally, you want to return all the fish & do a proper fishless cycle. <BTW - how do you know your cycle is "close"? do you have levels?> Next best is to keep a couple fish & finish the fishy cycle. The hardest is to keep all your fish & complete the cycle while treating for ich.
My suggestions:
1. Check your water parameters - ammonia & nitrites at minimum. Do as much pwc as needed to keep ammonia less than 0.5 & nitrites less than 0.25. <Eg, if ammonia is 1.5, change out 2/3 of the water. Make sure water is dechlorinated & temp & parameter matched when doing large pwc.>
2. Do the parameter check & pwc EVERYDAY until the cycle is complete.
3. Treat ich with either high temp (88F x 2-3 weeks), salt (0.3% final conc., increasing level over 2 days. Note you need to maintain the salt conc. during pwc's. This may get difficult when you are doing lots of pwcs due to the cycling tank.), or meds. <Quick cure is prob the best med for ich ... but again, when doing lots of pwc's it is imperative you maintain med concentration.>
Due to the need for pwc's during cycling, high temp with good aeration is prob the most fool proof method to treat the ich. All you need to do is to make sure the change water is at the same temp as the tank. <So when you get the temp up to 88, you need to heat the change water to that before hand .... or just use hot water from your tap if it is hot enough.>
