Last weekend I cleaned out my 55 gallon freshwater fish tank and moved it from the workshop side of the basement into the Man Room. First I emptied the tank, drug it outside and scrubbed it. I rinsed off the existing gravel. I wiped down the stand, placed the tank on top of it and leveled it. I then placed the rinsed gravel and several smooth rocks on the bottom of the tank. I cleaned out my canister filter and reloaded it with fresh Ammo Carb. After the two younger guys were in bed Son #1 and I filled the tank with fresh water, set the heaters, set the light, restarted the filter and walked away for 48 hours.
As soon as I got home from work last night we all piled into the van and headed out to one of three local fish stores. This was supposed to be an exploratory expedition. After visiting the other two it became pretty clear that this would be the place to purchase our fish. The tanks were very clean, prices clearly marked and the fish seemed lively according to their species.
Son #1 decided that Black Neon Tetras would be the first new residents of our tank (I did not take this photo):

Eleven of these guys currently inhabit our tank. They are schooling quite nicely. Their presence results in a very small amount of movement in the tank. We plan to add another 10-12 of two other species of tetra to the tank bringing the total number of tetras in the tank to roughly 30.
Once all of the tetras are in place we will at 4-5 angelfish to complete the tank. When we purchase the Angels they will be on the smaller side. This will keep them from intimidating the tetras. By the time they are mature they will get along nicely with their tank mates.
I’m a firm believer in the theory of keeping similar types of fish together. For that reason we will stay away from some of the faster moving or aggressive species of fish. I also will not overstock the tank. Many people will keep far too many fish requiring massive water changes to keep water quality to an acceptable level. Light feedings coupled with smaller numbers of smaller fish can make keeping an aquarium and easy to enjoy hobby.
I spent some time downstairs watching the fish after all of the guys were in bed. What struck me as amazing is the lifespan of the filter I am using to keep this tank clean. This ties back into my thoughts regarding keeping the hobby simple to enjoy.

While expensive (over $180.00 wholesale) this filter has run almost continuously since 1995. At 251 gallons per hour this pump has moved over 1,187,330,400 gallons since I plugged it in. What is truly amazing is this pump has required NO maintenance whatsoever other than changing the media. An amazing piece of engineering to say the least!
If you are thinking about getting into this hobby, don’t go cheap on the filter, go with something like my Eheim, you won’t regret it.
