BEHAVIOR OF TRANSPLANTED HEARTS IN PLATYFISH*

Platy Temperament / Behavior : This is a good tropical fish for the beginner

One retailer told me I should of taken out the bully guppy for a whileand when I added him back, he would of been the new fish in the tank,and perhaps would of behaved better. The only reason I chose the platywas
Platys are schooling fish, so that type of behavior is normal on any occasion.

We have one male platy who is actually the father of the four female platys in our tank who are about five months old. Mom died and I have to say it was a monogamous relationship between her and dad. He ignored the other female platy in the tank totally. We ended up giving her away with some other former babies. When mom died, dad spent three days just circling the tank. As his girls got older, he would make some attempt at contact but they actually seem to want nothing to do with him. They function as their own gang. He has taken to hanging out with the catfish but often seems isolated. We are not seeing any of the “courting” behavior we saw between mom and dad. We feel sorry for the guy. pregnant platy behaviors - Fish Tank

The pregnant platy will behave pretty much the same as she does normally. There are no distinct behavioral changes to look out for. Like other live-bearing fish, she carries her fry until they are fully developed. The gestation period typically lasts for around 28 days.Telling platy preggers Thank you for your very informativesite. I am a fish novice, and have just twoplaties. I am thinking that the female is pregnant, but I amnot sure. How can you tell? She looks plump, but are thereany other tell tale signs or behaviors that I should be looking for? I appreciate any information you canshare. Thanks! LissaPolymorphisms in reproductive strategies are among the most extreme and complex in nature. A prominent example is male body size and the correlated reproductive strategies in some species of platyfish and swordtails of the genus Xiphophorus. This polymorphism is controlled by a single Mendelian locus (P) that determines the onset of sexual maturity of males. Because males cease growth after reaching puberty, this results in a marked size polymorphism. The different male size classes show pronounced behavioral differences (e.g., courtship versus sneak mating), and females prefer large over small males. We show that sequence polymorphisms of the melanocortin receptor 4 gene (mc4r) comprise both functional and non-signal-transducing versions and that variation in copy number of mc4r genes on the Y chromosome underlies the P locus polymorphism. Nonfunctional Y-linked mc4r copies in larger males act as dominant-negative mutations and delay the onset of puberty. Copy number variation, as a regulating mechanism, endows this system with extreme genetic flexibility that generates extreme variation in phenotype. Because Mc4r is critically involved in regulation of body weight and appetite, a novel link between the physiological system controlling energy balance and the regulation of reproduction becomes apparent.Platy Parasite? Help needed for treatment. Hi again, Iappreciate always getting good advice from you guys - I hope you canhelp me again. Here's the setup: I have a 5g tank with afilter that has a carbon filter pad and a bio-wheel. There are 3platies in the tank - 1 male that we've had since7/25, and 2females since 8/14. The females both gave birth about a weekago, 3 days apart, but the babies are in a separate tank (and doingjust fine). The tank has been set up about a month and I waspretty sure it was well cycled, all water levels werefine. Our water is from a well, so very alkaline and veryhard. Just after the females gave birth I noticed their feces wereoften white & stringy, sometimes clear. I had I wasadvised not to treat simply on that "symptom" but I watchedthem carefully. They were still very active and eating well, and lookedgenerally healthy and happy. Early this week I noticed thatone of my females was hiding a lot, and that both females had a singlewhite spot near their mouth. I watched it over the course of a day andit was getting larger. My male also seemed to be actingstrangely - laying his fins down and just being much more calm thanusual. Though most of the time they were all active and definitely wereall eating well. But based on the behavior and thespots, I assumed it must be a parasite and treated withCopperSafe on the 24th (which I've had very good luck with in aprevious tank when my male platy was new). Before treating I removedthe bio-wheel and kept it in a plastic container with water from thetank. The following day I got a spike in Nitrites, which Iassumed to be from removing the bio-wheel. I started doing20% water changes daily starting 24 hours after treatment. Icouldn't get the Nitrites to go down, so I put the bio-wheel backin yesterday (the 27th). I haven't even gotten totesting the water yet today, but I woke up to see one of my femalescovered with white spots! First I thought Ich, but theymight be worms... I can't get a good look. One was kind of"hanging out", which is why I thought worms. Andthe "spots" sometimes seem to protrude more thanothers. All the fish are energetic (no more hiding out) andeat VERY well (though I reduced feeding because of the Nitritelevels). They look great, except for the very obviousparasite on the one fish. Could it be from the waterchanges? (reducing the amount of CopperSafe in the water) I thoughtI'd be better off reducing the amount before returning thebio-wheel.. but with Nitrites going crazy, I thought it worth the riskto put it back anyway. I'm just confused and not surewhat to do next. I also though it possible that the meds maybe forcing the internal parasite to the surface and maybe thisisn't such a bad thing. But I've seen no change since thismorning (it's been approx 6 hours). Any help with this would bemuch appreciated. Jennifer
