ok so i addid another oscar in my tank and the albino and the tiger are acting wierd there locking jaws biting at each others side but not hurting each other and now my albinos vent is sticking half way out since i added the tiger three days ago but hasnt laid anything i have a pleco in there with them should i take him out or leave him in please help i dont know what to do

how old are you Oscars? I'm a little confused, have you now got three Oscars? it sounds as if you are describing the female, the males sexual part is a lot more difficult to see them the females.

Occasionally, their sexual organs will protrude if they are performing a breeding courtship. However, it certainly not a guarantee that they will start laying eggs. The conditions in your tank will be very different to what it's like in their natural environment. Some fish will lay on a regular basis, others will just do it intermittently. You're just going to have to wait and see what happens

i have two ten inch oscars and two 6 inch oscars and a pleco my wuestion is should i take out the pleco

if you really want to succesfully breed your oscar they should be house alone without any tankmates. the pleco being nocturnal will definetly be a threat to the eggs as will any other fish inthe tank. if the parents feel threatened they might also eat the eggs themselves.

so i got rid of the pleco and the other two oscars to the lps now i only have two oscars in the tank and some feeders i feed them pellets frozen krill and once in a while feeders so well se what happens from here if there is anything else i should know please dont be shy let me know

if you actually have a mating pair you can encourage spawning by feeding more live foods for about a week then at your water change do a larger than normal one and replace the it with water a little cooler in temperature, say about 3-4 degrees. i have tried this and it worked for me.
