Pretty much so except for the far upper back right hand corner he allows the lone Gourami three times his size to reside. It's been rough trying to get it back in balance after I had to throw everything out and start over after a snail invasion I couldn't manage to get rid of no matter what I did. I finally scraped everything and started over. That left some giant algae eaters with a lack of algae to sustain themselves and they died. Everything else was so big that every time I tried to introduce new algae eaters they kept eating them.

I ended up with another snail invasion this past winter that must have come in via on a fish I bought but being more knowledgably now I immediately tossed everything except the reptile house because you can scrub every inch of that. So only experienced fish stores from now on, they may charge an arm and a leg for a fish but it's less costly than replacing everything.

This fella isn't half bad if he'd only not be so aggressive. It'd be interesting to watch how he rearranges everything when I clean it twice a year. That' not easy either, lots of heavy lifting involved so having to clean it more than that would be a pain.
