one of my guppy females has some little white spots on her tail fin and I just noticed today (so they can't have been there for long- might have even started today). Is this ick?

if it is can someone help me out with what to do?

they are like a grain of salt, and yeah it is in the same tank.

I don't think this is the same thing as what killed my betta though as that was fuzzy and really quick. This case the guppy is still very active, whereas the betta was listless for the few days before his death. And none of the tetras that died showed any white spots- but I definitely realize it could still easily be from them.

Salt-like spots = ich.

Between all the deaths you've had in the tank, I'd say you have stressful conditions in your tank. Fish coming down with different diseases is either from poor water quality or from stress. Perhaps you're just not seeing the signs of stress in the tank.

You should definitely run your tests again for nitrates, nitrite, ammonia, pH, etc. Are you using CO2 in your tank? If so, you'll need to find out what the swings from day to night are (measure just before lights on, and just before lights off).

hm. Well I don't have a pH test kit, but I will find out what my city water's is and I assume it should be around there. And I don't run CO2- I use Excel, but I dose it in small doses so I don't overdose. I will check my amo,trite and trate right now.

What do I do to get rid of ich, and is it contagious?

TEST RESULTS
amo: zero
trite: zero
trate: 10ppm
temp: 80F

That's a pretty big assumption.
Ideally, yes, your tank should be around there. But you won't be sure until you test for pH. For example, your water company could be adding temporary alkalines to the water to help prevent pipe corrosion. This typically results in a higher tapwater pH which then, over time, drops as the tapwater is no longer under pressure (i.e. from being in the pipes). Another possibility is that there is a lot of CO2 in your tapwater, resulting in a lower pH. Once allowed to sit in your tank for a while, the pH will rise again.

You will not be able to detect these potential swings in pH with any degree of accuracy until you start actually testing for pH.

Highly-contagious to your other fish, yes.
I'll tell you the solution that has worked best for me, but your plants probably aren't gonna like it. Raise the temp. up to 87 degrees F and add 2-3 tablespoons of aquarium salt for every 5 gallons of tankwater. Some may recommend using less, but I've not seen any ill-effects using this particular dosage amount.

I typically go about water changes as I normally would, but performing more with thorough vacuuming should help get rid of the ich from out of the gravel. You will need to replace the proper amount of salt when doing water changes.

Generally the visible symptoms of ich will disappear within a few days, but you wanna make sure you keep treating for it a good week or so after the last sings of ich have vanished completely.

hmm... yeah my plants are not going to like that. Ok, so I think when I go buy my pH test kit I should buy a little 5G tank to temporarily house my plants I guess. This is the worst time for this to happen lol. Murphy's Law I guess :).

The fish with the ich just had babies today, and I also have those five survivor fry- will they be able to adapt to the sudden salt shock?

EDIT: I decided to put my plants into a few 5G pails and place my strip light over them so they still get the required light. I will start the dosage tonight after I put the plants in the buckets. I am worried about my fry, but I guess with no places to hide they will be eaten anyways :p.

So to start the treatment, I should probably do a water change and then add the salt into the water I will be putting back in? Do I start gradual, like add only 1tbs per gallon and then later add the rest, or how do I do it?

Well ich, is something that can be caused of stress to the fish, or it can be carried by other fish to your tank, truth is that most of these methodes of ich are pointless. i tell you why raising your temp aint good idea, one it may cause more stress to the fisha and to you one the risk of shocking your plants in the tank. my best bet on this ick issue is to put your fish witht he ick in a QT tank witht he same parameters your main tank has. have no gravel and bare bottom and have airstones and a filter so the deal is that the ich will fall off after a couple weeks. so if the fish is heathly he will fit off the ick juist fine. if you leave the fish with the ick in your tank the ick will fall off and start all over agin since ick needs a host to live.

hmmmmm.... is it possible for ich to just go away? Or that those white specks were really something else? I looked this morning and none of my fish have any white spots at all, and I have been watching closely for a while on each fish. Is this a bad assumption?

ok, well one male guppy has finrot, and suddenly one of his side fins has this big white clump on it, inhibiting his swimming. I am improvising a quarantine tank for him- it is roughly a 1.5G glass container, and I put roughly 1/2 a tsp of aquarium salt in it for him to sit in I will be doing a water change each day for him to keep it aerated and clean. I will also be putting a big bunch of anubias barteri in with him to keep him feeling at home.

Please, if this is a bad idea let me know ASAP so I can put him back in the main tank and keep him happy.

well the white blob on his side fin is going away- whether he is fighting it off or the salt worked I don't know- and his fin rot seems to be going away as well. I will do another water change and up the salinity a bit and make sure he is cured and then put him in the main tank again.
