Are you talking about the fish in the background of these pictures? What size tank is this in? The one in focus I am 90% sure is male, in the last pic off all his fins are displaying except analfin, making me think it is indeed a male.
The one in the background looks to be a female.
I agree with @Rtessy I think you should be looking at GH/KH in your water. I recently found mine was non existent and my plants/fish/invertebrates were suffering because of it. There are ways to raise this but first you should test to see what your water sits at and we can decide where to go...
Just wanted to point out something about that rectangle decoration you have. I have the same one and with small fish it's no problem but be careful of fish that are big enough to get stuck in it! I have lost a fish because they swam into a hole they didn't fit in. Just wanted to warn you!
So probably the stress of my bad water changed could have made her susceptible then? That would make sense. I feel terrible about it, water temp changed in the time of my filling the tank back. I think something pulled hot water somewhere else in the house and it dropped the temp.
Hey guys, my Swordtail died very suddenly last night. She was fine the day before and yesterday I noticed she was very slow, still in control of her swimming just slow and rigid. This is what she looked like. Her body looks full of redness. She was a little bloated but not much. I have treated...
Mollys will change there colors to there environment over time. For example if you have a Dalmatian Molly and put it on a black substrate it will eventually turn almost completely black. It looks like yours has the darker pigment coming in. With Mollys breeding so often and so much and so many...
Like @KingD said you should be fine doing it that way. Also, just doing it shortly after you begin to fill. The movement of the water coming in will also mix the prime around the tank. Having that small amount of untreated water enter the tank for a very small amount of time wont hurt anything.
This isn't a problem. I just pour the prime when I start filling the tank back up and pour it right next to where the water is coming in. I also leave my airstones running so the water will be mixing with the prime throughout the fill.
You have an aerator! There is a tool to remove it which you can find at your hardware store. When it's removed you will see the threads. You can then bring the aerator to your store and they be able to find you a adapter to work with the python if the supplied one doesn't fit.
Also Hygrophilia does the whole "cut the stem and two new will grow" thing like clock work. My bunch is currently about 15 inches tall. I really need to cut mine back even though it scares me to do so.
