Ok I would like to stock a tank with 2 oscars, 2 jd's, 2 sevs, 2 eclipse cats, and a pleco. I have read posts that all these would be good tank mates but would love to hear opinions. I currently only have 2 eclipse cats in a 75gal they are roughly 4" which is about double the size they were when I got them 4 months ago. Soon I will be making a custom large tank for a permanent home. What size of tank would I be looking at to house all these fish comfortably?
