thats a beautiful oscar!! great job on the save he has some great color to him!! n yeah all that pouting is typical O behavior i wouldnt worry about it too much an O that size may take a little while to acclimate but once he does he will have no problem getting his fair share of food lol, n yaeh just keep the water as clean as possible and that HITH should clear right up, it doesnt look like its too bad so thats good you got him when you did
