hey, congrats on finally getting some action goin' on in your tank...
The issue with adding 'too many fish' at once is a coupel issues...
First, if something goes wrong, or maybe you didnt read or do something right, then the chance of total loss is pretty significant...
Also, the 'cycling' process is not something that happens all at once... that is, now that your tank is 'cycled' it doesnt mean you can put a ton o fish and critters in there..
the cycling process setup the 'initial' biological organisms... the population is relative small/low as there isnt much for them to consume, and there fore they only multiplied minimally..
as you add more and more fish, (gradually), the organisms get a new food source and with the new and more plentiful food supply, the population of biological organisms grows, to handle the new 'bio load'
they will continue to grow until they find the 'balance' of food to organism level...
and as you observed in your test results... the amount of fish you added was more then the organisms could deal with.. which is what led to the higher ammonia result...
You did great by doing a quick water change to reduce the ammonia, but ammonia is very caustic and will burn the gills of the fish... how much, I dont know... maybe very little to none...
The goal is to go slowly and to build up the organism population so they can help in preventing issues...
as for the nitrate.. they arent a big concern now, as it really only matters for corals and such...
The skimmer... you could probably have waited, or not, depending on the deal....
as for posting pics, you can post them two ways... you can look just below the text entry box for replying to messages here, and there are several text fields where you can browse to locate the filename and then when you are done, you click on PROCESS NOW to upload the pics and then you need to click on POST when you are done...
PLEASE make sure your pictures are smaller then uber high resolution... you really only need a resolution of 640x320 for the majority of web pictures....
The other method is to open a
www.photobucket.com account, (or any other photo web hosting servers), and upload your pictures to thier servers... (it is free)... and this allows you to have a back up of your pictures, and to share your pictures, and or protect your pictures with passwords, and this will save me and my web hosting server some major space...
I suggest you check out
www.photobucket.com and look around there...
im sure you w9ill like it, not only for fish and aquarius but for all around general picture sharing...
