looking at the pics of the platy it is the female i lost, unsure why, water quality is good, i think she may have not been well when i got her, cause she kept hiding, and didn't really seem to eat..... only had her since the 22nd, and all my guppies and other fish are doing good, the other platy have had hime for awhile and he is very healthy.... i am trying to figure out right now what kind of cat fish i have, didn't see one like him in the pics, want another cause they are excelent for helping to keep tank clean, he is light grey mostly with darker grey on the top if this helps..... isn't the nicest looking fish, was given to me by a friend, that is why not sure exact kind, and with a 20 gal tank recommend 2 to help maintain cleaner gravol, with 10 gal tank always had 1, plus when i get new tank pland to move some of what i have to larger tank accourding to type, and water trmp, cause they vary somwaht fish to fish, and the ones that prefer warmer water want to put in a tank that can increase temp, while keeping spiecies that prefer bit cooler like platties in a tank that has bit lower temp, kinda surprised that platiess are trop[ical concidering tey prefer the water to be about 21 - 22 degrees celcius, anyways if anyone has idea what sort of catfish i have let me know, want to make sure same spiecies, my care worker has to pick it up since i am unable to go due to por health, got fish so i would have something to help pass the time at home that i always enjoied, since can't go out anymore
