I agree. The only reason I asked about the severum was that I have read on some sites that they only get to 4-6inches and there has been a green severum at a local pet store that is about 5 inches or so and seems like it hasn't grown for the the past 6 months that it has been there. What sizes do you find they generally grow to? also the tank I was going to be keeping the carpintis and gold spot pleco in is a 48"x18"x18" do you think that is big enough?
I think the best option for myself would be to not keep any of the carpintis and have a more peaceful cichlid tank.
