They could be trying to get rid of parasites. What size and temperature is your tank ? Exactly what and how many fish are in it ? Any new fish or plants added lately ?

Try bumping up the temperature to about 82 for a few days. If the problem is Ick, that might be all you have to do. Keep an eye out for any spots or discoloration. Let us know what's going on from time to time. Good luck.

Good luck, keep a close eye on them, and let us know if you see any other symptoms develop. . . :(

There are several possible reasons, which you (we) should explore. Flashing [the term for what you are seeing] can be caused by gill flukes, ich, velvet and other parasites, ammonia, nitrite, nitrate, and inappropriate GH and pH.

Which fish species are doing the flashing?
What are your water parameters, meaning GH (general hardness) and pH?
Have you tested for ammonia, nitrite and nitrate?

OK, this is starting to make some sense, if it is just the mollies.

First, on the GH and pH of your water, this you can ascertain from the municipal water supply folks; many have a website with water data posted. If you find it and can't decipher it, post the link and one of us will check. Water params are vital to mollies, and the flashing might very well be due to this.

As for the ammonia, nitrite and nitrate, your fish store should be able to test these. But please ask them for numbers, not some generic term like "looks fine," or "is a bit high but OK" which tells us nothing. Numbers for tests, always, is crucial.

Other very important questions...how long have you had this tank running? And how long have you had the mollies? And when were the last new fish added, if other than the mollies?

I have the tank since the beginning of last month and let it run for a week then i cycled it. after that I got 2 tetras and 2 Mollies. Tetras are doing great! 2 weeks ago i just got 2 ballon belly. Those are doing fine.

I need the other information I asked for, please. Diagnosing a fish problem is not easy, as there are so many factors. When you get sick and go to the doctor, he can't help if he doesn't find out all the facts. So here too.

But, having said that, the short time span of new fish would tend to suggest a parasite, and likely ich. Raise the temperature to 86F and keep it there for a week. Carefully observe the fish to see if any white spots appear; these usually first show on the fins. Ich first attacks the gills where we can't see the spots, which is why the flashing is indicative as a first sign.

But again, many other issues can cause flashing. Only 3 weeks ago I had to deal with gill flukes [interestingly the first time I've seen this disease in more than 20 years] and the first indicator was flashing. It is always wise to check everything to avoid incorrect diagnosing and treatment, as this can make the problem worse if we err. For instance, with gill flukes the second symptom is very increased respiration, and in this case, raising the temperature makes it much worse because the fish are already having trouble getting oxygen, and the warmer the water the less oxygen it holds.

I have had the tank since the beginning of last month (april). I put fish in it a week after i set everything up...then did the cycle. then started to put more fish in a week after that. I jI have had the mollies for awhile. I just got 3, 2 weeks ago. 2 0f them have been acting up. and an older one i have had has too. and will raising the temperature affect any of my fish including babies??

Need baby help!

My tetra just had bout 10 to 15 babies. I have them in a container in the tank. Now my mollies in my tank may have the ich so im raising my temp up to 87 degrees. will this effect my babies any??

Edit by Byron: I came across this post starting a new thread and as it was closely related to the present thread, I moved it. It is always better to stay with one thread on a topic, to avoid duplication of effort and provide better advice since everyone is on the same page as it were.

Didnt mean to send the last message. never saw yours. But i do have babies and i dont want to harm them. Will raising the temperature affect them? I know when there more heat theres less oxygen.

If raising the temp cures the fish, the loss of the fry is immaterial in my view, and that is not to say they would die. I assume these are molly fry.

But you still have not given me the other data asked for, and we are still making assumptions. Though from what you have told us, I think ich is the likely issue. But even so, inappropriate water parameters will only make this worse to deal with as the fish are under further stress.

Agreed, the loss of fry is inconsequential - there will be more. Lots more.

Ich is a problem waiting to happen and if conditions are not good or proper in the tank and / or the fish receive a sudden chill, your fish are much more likely to be infected. That, and the possibility of another issue, is why the info requested is so important. My initial responses were admittedly knee jerk. Water quality is almost always the answer and cure for problems with fish.

You're right, and if you can add a bubbler to help, now might be a good time to do so. . .

That aside, I've been forced to heat-treat for Ich with newly born Molly and Platy fry in the tank, and neither have come to any harm from the heat. Much of this depends on the health of the fish to begin with, and how sick they've already become - as well as water quality, stress, and genetics. . . nobody can guarantee that they'll all make it through, but they have a far greater chance for survival with the treatment than without it - and all future generations as well!

Please try to find the information that Byron requested, too. It is really difficult to diagnose a fish, any more information you can provide can only help - and hopefully they will recover to live a long and healthy life in your care :)
