I haven't checked the ammonia and nitrate levels before so I guess I need to buy the stuff to do that. The temp is 76 and the tank is a 29 gallon. I did a water change and gravel vaccuum early last week and added a few new rocks. The previous change was probably about 3 weeks before. I have not had any problems with the tank since it was set up and I am not on a consistent schedule for water changes. I usually only change about 5 gallons of the water at a time. The following fish have been in the tank for well over a year.
1 sword tail (my baby) - 1.5"
2 Black tetra - 1.5" each
1 red eye tetra - 1"
2 gold barbs (i think) - 1" each
1 red fin shark - 1.5"
2 neon - 1" each
Last week I added the following fish
2 kissing gourami - 1.5"
2 small pleco
1 swordtail 1.5"
3 little bitty fish that I can't remember but they are only a little over .5'
I'm guessing that the problem has to do with the new fish but I'm not sure. Would the new fish effect the levels in the tank even though it was already a well established environment? All that I have done so far is put some salt in the tank. I was thinking about treating for ich, just in case but I wasn't sure if that was a good idea, and the bottle said not to treat tetra's so I wasn't sure what to do about that.
I was also wondering, if I don't have another tank how do I put her it
QT? Don't I need to keep the heater and filter going for her? Thanks again
