@ Phaelax:
I used to have up to 5 tanks running at once, once upon a time. I no longer run any tanks at all; once I found out that the little bit of ammonia (fish waste) that got into the air caused a small allergic reaction (puffy eyes, runny nose, etc.)...especially during water changes. Which rather sucks, as I thoroughly enjoyed my tanks.
Good looking setup; looks like your running close to 27 inches of fish total, so just under the max for that tank. Live plants will help a lot. If you can get your hands on some simple crypto, you will get a nice grouping of additional plant coverage that I'm sure all your fish (and the frogs) will appreciate. Crypto does well in most lighting, depending on the depth. How big does that Pleco get though? If it's more than 6 inches total; I would think about ditching that choice, perhaps get a small school (6 would do it) of Corydoras? They're good bottom cleaners, and fun to watch (very social). I actually inadvertently got a breeding pair from Wal-Mart; which I used to breed quite a few fry with (then traded them in at a local fish store for store credit). Breeding egg-layers is quite a different experience from live-bearers.
If you're worried about not having the Pleco around for algae cleanup; try to get some
Amano Shrimp. They do just as well for algae cleanup (aside from your snail), and don't leave such a large footprint on your system. Another thing to consider; if algae isn't abundant, and you're not feeding algae disks to your Pleco, he
will suck off the slime coat from some of your fish (experienced this myself)...which will also stress them out, and potentially cause an "ich" outbreak.
That's also a handsome stand you have created. I always wanted to make my own set-up as well; but never got around to it. One thing you might think about, is a simple Co2 system for your plants; or something like this:
Flourish excel. Using Flourish Excel will negate the need for a Co2 System with hardy plants (like your banana plants, or crypto). A small dose a day will do it. One bottle should last you nearly a month (give or take).
What kind of filtration are you planning on? I used to be partial to bio-wheel filters (such as Penguin systems).
Be sure to post pics of the tank in stages of completion, including the final setup.
