Just today about 3 hours ago, I fed my O and Jack. Then I put 2 slices of cucumber in the tank between the gravels. For some reason it seems to weigh down the cucumber and keep it there (First time feeding cucumber

) . I turned off all the lights and went downstairs. I came upstairs after 2 hours and turned on the nightstand light so and shown it to the tank a little. I could seed my pleco eating the cucumber which I was so excited about. But then, my O came and attacked the pleco. I mean tried to bite the pleco. Then my pleco ran to the side of the tank. While the pleco was minding his own bussiness sucking on algae on the glass, my O came to bite at the pleco again. Then, my pleco went behind the filter. After a while, my pleco went to the other side of the tank and the pleco tried to bite it again. My pleco went back on the gravel to eat the cucumber but was later attacked by my O again. My pleco went to the side of the tank again. Then the O attacked again and my pleco went to the heater and stayed there. That's when I got on the computer and decided to post this up

Sorry I had to go in so much details. All that just happened in the past 30 minutes from when this was posted

. So do you guys think I should separate them? I really don't want to buy a new tank. It costs way too much money. But if I have to... I'll see what I can do. Btw the pleco is an albino chocolate pleco which is very shy and is about 5-6 inches where as the O is 4-5 inches. I really think my O got bigger in the past month since I got him and might be 5-6 inches since it seems the same length as my pleco.
