Anybody keep "natural" aquariums without filtration? Here's a couple that I recently took down:

5-gal


2-gal bowl

I have read about them but have yet to try it myself yet, yours look nice.
How well did they do? Are they truly stable tanks only needing top offs?

Did a couple with Killifish haven't tried with any other kind of fish. They are really neat though, I personally enjoyed them,

dang ....Awesome tanks

When i come up to Richmond I need to get some pointers ...love the guppy bowl

Very nice!!

Ok so they are really only good for shrimp or small fish with light stocking. How often do you do pwc's? and of about what percent?
Sounds like it would be perfect for a 10g with rcs only in it.

A 10 gal could hold some small fish PLUS the shrimp, I think. I did 50% PWCs once weekly, which is what I do on all my tanks. I don't think that schedule is necessary but it is what I have done for so many years that it is just habit. Maybe 25% per week, or even every 2 weeks would be fine. The main thing is that the plants are healthy and growing well - then you know they are eating up the nutrients and supplying oxygen to the fish - no water movement required!

being a planted tank dude, I really like those tanks.. is the red plant brzone wedtilli? cryptocoryne? it would be nice if you could tell me the name of the red plant thanks.

Nice they look so natural, nice to keep some shrimps and small fish.. great pic!..

I've been contimplating this for while for some shrimp tanks. They would be just regular 10g tanks. Did you dose any ferts in the tanks? Right now I use both EI and PMDD mixes and would probably carry over one or the other to the "el naturale" tank. Most likely PMDD to be safe to start.
