75 gallon Planted Office Tank Journal

Yesterday afternoon (Friday 04/02/10), I checked Ammonia again, still 0, so I really think the seed worked well as an almost instant cycle. The filter was removed from my kid’s well stocked tank and hooked up to new tank, and fish introduced, within 45 mins. I hear that the bacteria may survive without fish for a day or two, but I don’t know how accurate that info it. I didn't want to risk it and certainly 45 mins is a fast switch out, so I think anything that had colonized the filter certainly survived, plus the fish waste has managed to keep it alive.

I had to cull one of the cherry barbs on Friday, one that would not have made it until Monday I think. Others are very active, playful, and seem to really enjoy the 75 gallon, even though it is amazing bare.

I just picked up a few more cherry barbs, and I'm acclimating them now.
 
I think 3 or 4 Roseline Sharks would be cool :)


I always had the impression that I should avoid anyting with the word "shark" in it, but I googled "Roseline Sharks" at your suggestion. They are very pretty indeed! I think they get a little big, 4.5", so I could not have too many of them? How many do you think in 75G?

I have a feeling I am probably going to end up with just a tank of cherry barbs, LOL. I'll have to see how nice they look against a planted (green) backdrop.
 
Checked ammonia yesturday and took a quick trip to office today, ammonia zero both days. Have about 13 cherry barbs in there, and I am adding two more tonight. The two are coming from my kids tank, and they are the original fish from the cycle of that tank over a 16 months ago. I think they will be happier as part of a large school, and my kids like the idea of making room for a new fish.
 
must say i have to agree and i think you should add some Roselines i think in a 75 you could do 4 of them but not completely sure. if you do go with them get smaller ones because thay tend to be cheaper compared to adults (i've seen them for $40 each af full grown).
 
Something to keep in mind is that roselines prefer a bit cooler temperatures so it might be worth accounting for that depending on what other livestock you choose. Also, 4 would be the minimum as they are a schooling fish.
 
Bunch of equipment coming in today, hopefully I will have photos. Cherry barbs are looking very happy.

I have a question regarding a thin film of oil (maybe fish oil used in the fish foods)? I have this thin film, which has not broken up or broken down since I filled the water. Since this is very little surface water agitation, I think it forms. It will never make it into the filter, since it floats on the surface of the water. The question is, is this film common on planted tanks, where surface agitation is limited due to co2?

I am also under the impressions that when the co2 and lights are off at night, it is okey to turn on some form of aggitation? I plan on using a power head aimed upwards which would stir around the surface level water, and hopefully make this film less visible. Please let me know your thoughts on this matter.
 
Cherry barbs are fast little fish, I am having a hard time getting a close up in focus. Here are my bad attempts:
