| || | New Guppy Aggression And Guppy Tail Turning Clear
Hello, about 3 weeks ago I did a full water change of my 10 gallon fish tank and I cleaned the WHOLE tank in one night. During that night, my fish were sitting in a 5 gallon tank and they are all doing fine! Showed no signs of major stress, except my molly but she is fine.. That was 3 weeks ago anyways, probably 4. Anyways, yesterday I decided to go and buy 1 more Green Cory Catfish and 1 more guppy. The catfish get's along fine with the other but the guppy, he tends to fight with my alpha guppy (the guppy that acts like he owns the tank). My alpha guppy, he chases around the new guppy, looks like he kisses him sometimes and this is non stop. Also, the alpha guppy, his top fin is getting a bit clear.. I noticed this yesterday and for a while now his back fin has been getting a little clear at the end but it hasn't been getting any worse. Should I worry about his top fin getting clear? He is a guppy that acts like he is in charge of the group.. It doesn't look like the fin is ripping off, just getting clear. I read about this before and it said that this is normal? This is a 10 gallon, heated, and filtered. Temp stays at 78F. I have 2 Green Cory Catfish, 3 Male guppies, and 1 Marble Molly. Are they being aggressive because he is a new fish to the tank? I've seen aggression before when adding new fish to the tank but it stresses me out when I watch them fight..
