    Hello, all. Long time no post...guess that's what kids and work do.

    Anywho, I had a thread started here of me cycling and stocking my tank. It's a 27 gal Cube (20 w x 20 h x 18 d all inches) with an LED light on top. I went 17 months without a loss of fish, one died of causes unknown to me in Nov. '12. In December I wanted to try something new, so I found a couple on craigslist who came and took the 20 serpae tetra and the ABN pleco and added them to their 55 gal they had just finished cycling and started to stock.

    Just to update on what is running in there, About 6 months prior (June '12) I had added an Eheim 2211 (rated for 39 US gal) as an additional filter. I doubled the biomax, adding the original amount from my AC70 and the additional new biomax all the the canister so it was packed with biomedia from top to bottom. I also have a killer pre-filter sponge on the Eheim which I've posted about prior. I then just stacked three AC 70 sponges (still the original sponges are in use I bought and put in when I first got it) and removed the prefilter on the AC70 so that thing is a mechanical filtration workhorse.

    I've continued to maintain 60% water changes every week, and continue to test my water once a month. Crystal clear all the time minus the algae I leave in spots. 78 degrees all the time. I've meticulously kept a journal of weekly water changes, observations of fish behavior in response to changes in light, amounts or frequency fed, redecorating or adding/removing plants, fertilizer amounts and frequency and plant results, yada yada get the point. I've never had a real "spike," crash, etc of any sort since I completed my fishless cycle...Ammonia and Nitrite are always 0, and the Nitrates never get above 20, and pH hovers around 7. Same results every month when I test the water before a water change. That's testament to the advice and patience shown to me on this site when I joined, so kudos to the staff and members!!! I've really enjoyed this hobby as a direct result of your input here, you all probably remember my constant questioning.

    So back to this past December.

    I re-homed the stock in the tank. Then I went and picked up two Black convict juveniles from a guy in a neighboring town who had a gang of them to get rid of. And whoa are these fish fun. They know when they are going to get fed, and beg worse than our dogs. I'm thinking one is a male and one is a female, because one is literally twice the size of the other one, and the large one has a hump on his forehead like I've seen in some pics on-line. He is like three inches long now, not counting his tail and veils, if that's what you call them. The other one is smaller, much quicker, and his some vivid blues that show up on the fins when it flares up at me through the glass. Both are terribly healthy, colorful, and eat like pigs.

    If they do end up being male and female and pair off and spawn, I am going to return the male to the guy I got them from, he said that wouldn't be a problem. Only time will tell.

    In the meantime, that's what brings me to posting an update and looking for input.

    Can anyone think of anything that would be safe to add as some sort of dither? The larger one hangs near the bottom center of the tank where some driftwood set up against each other has made a cave and the other one cruises around freely. They chase each other around now and again, but really it's just right before they get fed. I'm looking for something, like 6, 8, 10 fish that are quick and hardy enough to swim with one or two of these fish? I do realize that in time and based on their growth that one, if not both, of the black convicts will move back or onto another tank. I'm just looking for something that would add to the tank while the convicts lurk in the shadows of the rock and wood.

    Oh, and I'll try and post some updated pics when I get a chance.

    Thanks for your time and input!

    Okay, so took advantage of leaving the kids with the sitter today on my day off.

    First thing this morning I moved the two black convict cichlids, both males, to a ten gallon aquarium with old tank water and a sponge filter. Then did my weekly WC, and adjusted the thermostat up to 80/81 degrees F. I took the two fish back to the source I got them and off I went. I went by the LFS and picked up two female German Blue Rams. The guy there has several breeding pairs in the back and he fills his tanks with the fry. Both healthy, beautiful specimens. Thanks to threads and pics here I was able to easily identify the males and females and went with two ladies. I'll eventually be back for a male and then will return the third wheel female if/when they pair up. I also picked up 10 Bloodfin Tetra. These things are gorgeous and fun as all get out to watch swim. They enjoy all the tank space there is and for the most part stick tightly together unless they spook then recollect. And they are always on the move. Really, really fun to watch. While I was doing my WC i redecorated a little bit and grouped some plants together, put some caves in there, and perched a piece of driftwood over top. The two GBRs stay near each other and seem to really enjoy the caves and bunches of plants, rummaging for bits here and there among the stems.

    In a month or so, as long as all the new inhabitants remain happy and healthy, I'm going back for a male GBR and EITHER 10 more Bloodfin Tetra or ten Flame Tetra. The gentleman had several dozen nice looking Flame Tetra. I think they'd be a nice contrast with the other fish, or 20 Bloodfins will look nice, also.

    I'm not concerned about how the GBRs will do with my water parameters (hardness, acidity, etc) seeing as how they were bred and raised in my local water supply at the LFS. I'm going to monitor ammonia, trItes, and trAtes daily for the next week to ten days to make sure I have no spikes and make sure the tank is ready for some more tenants.

    Pics coming soon.

    Any thoughts or suggestions on filling out the tank? Would 1m/2f GBRs be ok or remove the third wheel? Etc. etc.

    Thanks for reading!
