Fish is sick question??

Question

if i have a fish that has ich and i leave it in the fish tank till it dies and then i take it out, will other fish that i put in the fish tank like a week later will get ich too? or will it be normal?

overall, does the disease get carried on the fish or the water and does it stay on the water?

Answer 1

I personally wouldn't trust it. I would either drain & clean the whole tank & start all over, or I would treat it before adding any fish. I really love fish & wouldn't risk it.

Answer 2

Yes it is a water bound fungis and you should change the water and put Melafix and Pimafix in it and that should clear it up.

Answer 3

As soon as one of your fish shows ich, you can be sure that all of the other fish in the aquarium have been exposed to it.  Whether or not the other fish contract ich depends on their individual immune systems.  With lower water quality, your fish's immune system is lowered and it is more prone to infection by ich.  But, yeah, all of the fish in that aquarium Have already been exposed to ich.  Ich is present in many fish tanks, in fact, but the fish's immune systems are enough to fight it off.  

You should take these following steps.  If you follow the instructions listed below, your sick fish will recover and your other fish will not catch the ich.  Instructions:

1.  Add aquarium salt to the water.  I have bettas, and I use four teaspoons of aquarium salt for every ten gallons.  If you tell me what fish species you have, I'll tell you if the salt requirement is higher or lower.  This aquarium salt is good for the fish and bad for the parasite, so there are two reasons to add it to your tank.  Also add medication rated to treat ich and with an ingredient called "malachite green" at 0.075%.  

2.  If you have tropical fish and a heated fishtank, raise the water temperature a few degrees.  My fish don't get ich any more now that I started using aquarium salt, but when they did get ich I added salt and raised the water to 80 degrees and it helped a lot.  None of my fish died, and the ich was gone in two days.  

3.  Perform normal maintenance on your aquarium.  The reason your fish contracted the ich was because their immune system was lowered, perhaps by stress or poor water quality.  Buy a test kit and make sure you don't have raw ammonia in the water.  Nitrites also stress the fish.  In a nitrogen cycled aquarium, the nitrogen is present in the form of nitrate, which is not very harmful to fish when compared to ammonia from fish waste.  New tanks are suceptible to fish death because there are not any nitrogen-converting bacteria established yet, and ammonia builds up and stresses the fish and they die of opportunistic infections or just plain ammonia poisoning.  So either cycle your tank or test your water for toxins.  Routine maintenance and regular cleaning is necessary to keep your fishs' immune systems up.  

To answer your question, ich is present in most water.  If you tested just about any aquarium it would be there.  The fish only contract it when they have a lowered immune system, though.  So add some salt at the concentration of four teaspoons per ten gallon (may be higher or lower depending on the specific fish you have.  I have bettas) and buy some ich medication that has 0.075% malachite green.  If you salt and medicate your water, your fish should recover in no time at all.  They're going to be fine  :)
