yesterday i got a female convict from my friend cause he needed his 10 gallon for fry. I put it in thinking if it caused problems my pbass would step in and my friends dad told me if there was aggresion issues to put a cup over the convict so i put a cup over it for five minutes and did my weekly water change now Flash (my pbass) wont move from one spot on the bottom,he wont eat anything,and has his stress colors. and its worrying me
