That's still horrific stocking I'm sorry to say. The frontosa and the yellow lab will destroy the grouramis if given the chance. 2 inch oscars can reach 12 inches each within a year. They are messy, fast growing, aggressive fish that need a minimum 500L tank for the pair of them with massive amounts of filtration. The 35L tank with two 2 inch long oscars is already overstocked.
understood with the oscars, I don't know if it was thought through, and seems to be more for the appeal for the younger kids. also I wasn't aware that they grew quite so fast, so doubt my parents are either.
Thank you, obviously was not aware of the incompatibility , also it is NOT a frontosa, I was guessing, its a blue dolphin/hump-head... however short of putting them in with oscars, or two large discus, there isn't much else I can do now, because my parents couldn't wait two more days.
I'm posting up all the info because I do appreciate the advice, and am not happy with our current setups, and believe some are overstocked and want to try and change it, so thanks for all the comments...
probably a common problem on here, buuuuut, need more space, need more tanks, need more money
