20G Long



This is my first real attempt in the aquarium hobby outside of what my family had for a few months as a child. I love technically complex and precise things and I feel that will bleed through with this project.


This aquarium was a rush upgrade from a free 10 gallon we received. The plan is for this aquarium to be an attractive display tank with a community environment. There will be cues from nature in the design.


I am using a HOB AquaClear with mechanical filtration covering the intake as well as being the base for the chamber, followed by polyfill for water polishing. I use a bag of Purigen for chemical filtration and Matrix for the bio-media.


I am going for medium lighting with the Finnex planted+24/7. I will play around with it if I find adverse reactions on the 24/7 mode.




This is a planted community tank. There are currently and abundance of live-bearing fish in the form of Endlers and Mollys. The False Juli Corries are probably the most fun to watch but when the light hits the right shade my Flame Dwarf Gourami just glows.

I had a CPO who unfortunately passed, Scary Terry, I plan to replace him once I am confident the environment is completely secure for him.

I am using a cutback version of the E.I. dosing concept with daily doses of Excel. In the future I plan to adopt to either DIY Co2 or pressurized.

Feeding See more

New Life Spectrum · Algae Tab · Flakes · Frozen Bloodworms
I typically feed mostly New Life Spectrum pellets, while feeding quality flakes and a couple pieces of algae wafer.

I will spice things up about once a week and feed frozen blood worms.


I am currently doing 30-50% water changes once or twice a week, vacuuming the pebbles as I can and scrubbing the walls as often as possible.

On average you perform a 29.4% water change every 3 days.

0% total water change in August.

Added 12 root tabs to the sides of the aquarium. Hopefully I'll notice some results. The rest of my fertilizers don't get here till Monday and in one plant in particular I am n
Fry Development

Today during feeding time I've noticed that the endler fry continue to grow bigger and more confident. Some are starting to develop quite the black body which is contraste
Cycle nearing complete.

Ammonia is now reading 0 and nitrite is a declining parameter.
After weeks of very frequent water changes this is a very welcome development.

Inspiration & Goals

The plan is to progressively make this tank a high-tech planted aquarium using the E.I. dosing concept. Also as a plan with this tank I intend to at times overkill in equipment continuously making it more technically complex. This may be furthered with use of UV, powered Co2 diffuser, potentially setting up a refugium or sump with as much being done inline as possible.

Disasters & Regrets

Unfortunately due to circumstances I had to do a complete fish-in cycle with a fully stocked aquarium. This led to many water changes sometimes as frequently as 3 times a day to keep the levels bearable. Unfortunately I still lost 2 fish, 1 being damaged on the intake filter beyond repair and the other sadly was my favorite dwarf crawfish that couldn't stand the conditions.
