Hi, i rescued to monster sized oscars today. I had been toying with the idea then when i found out that they were housed in a 75 gallon with a divider down the middle I had to get them today. I have them in a six foot 135 gallon tank. My Ph is a bit high for oscars but the guy who had them before told me that his ph was 8.4 so i think they should be ok in my water. Im pretty excited about them, i wanted to grow out my own oscars but the two times i tried to buy them from a LFS they withered and died , i believe the ph was too much for them. I did not think i would find any kept in higher ph for sale. Here they are, keep in mind their color is washed out cause they are pouting and stressed from the traumatic move. I think they should color up nicely in the next week or so. The red oscar is approx 10-11 inches and the tiger oscar is 12-13 inches. The red is the dominant one and also appears older . He certainly is heavier . I still have to measure them but didnt want to do it on their first day. I did tape up a fishing measure sticker on the glass and those were the approx measurements when they swam slowly infront of it.
