Ok, so I am really pretty new at this stuff. I have had a 2 gal tank for the last 2 years. In it I had a few danios (glo-fish) and near the end I had one who was a real bully. (I realize now it was because it was a tiny tank to keep danios in!!!) I found this great 29gal tank on Craigslist and bought it, it came stocked with fish and live plants and I have had it for about two months now.
I took my old fish and added them to the big tank after a week or two. My bully danio seemed to straighten right out and has been minimally aggresive.
I realized about a week ago that my beautiful angel fish had something hanging from his fin, I was sure it was fin rot, I went to the store and bought "Lifeguard all-in-one Treatment" for fungus, rots and ich. I thought this would be safe since I have never dealt with fish disease before. I have been treating it for six days and he seems to be doing much better! The medicine said to do a water change on day 6 (yesterday) so I did and then added the meds. I think this is working but I noticed this morning that one of my fish, I'm sorry I'm not sure what he is, (I can post a picture) has been hiding in one of the rocks when usually he is very active. Upon closer inspection I realized he has scales missing and a whitish area on his torso. I also realized with this that my bully danio from my small tank has suddenly been much more aggressive, especially to this type of fish, (I have 3 of them and he chases and bites them.) My worry is either I have another infection other than the fin rot or my danio is biting my other fish in which case they could become infected.
I am wondering if I should continue medicating with this medicine or switch it up or stop completely, I have no idea....
My water parameters this morning were:
Ammonia=1.5ppm (highest it has been since I have had the tank.)
Nitrate=40=80ppm (also highest its been.)
My tests didn't help my stress level and I am worried the meds are causing the spikes.
On a slightly related note, I think the whole reason I got fin rot to begin with is the fact that my filter is very low volume, I think I am going to replace it today and was hoping for some input on that idea and what filter qualities you would look at.
Thanks for your help in advance!
