So i've moved on from a 10g & 30 gallon tank to a 50gallon tank. I've made it a veritable fish paradise that is very interesting for myself and guests to my place. However I'm having issues maintaining livestock. Through this post (& plea for help) I may be confessing my own neglect on some level. I hope it can be used for others to learn from.
My biggest issue: No not algae, I'm okay with algae in my tank (a little bit). Its angelfish or my LFS (petco). The angels before I could not diagnose, no visible symptoms aside from eratic swimming and quick demise had been noticable. This last angel the same swimming and red eyes with red (truly pink) gills. I cant see any white worms or noticeable fungus either. I had not quarantined the two new angels and my one in the tank succumbed to the same symptoms. So i still have one angel, 5 neons, 1 CAE, 1 SAE. I'm aware the CAE may attack flat bodied fish without a food source. But there is plenty of algae and no damage to the body of the angels. I've also not ever seen an attempt at another fish from the CAE. I am setting up a QT tank now, as it seems that it truly is unavoidable.
My water temperature is fairly warm 82-84 on average. Perhaps this is stressing the angels (despite meticulous acclimation - fish eat and regain full color within an hour or less time after being added to the main tank).
Or is this a simple case of Petco/Petsmart poor fish stock that are riddled with disease?
I've been recommended LiveAquaria by a friend, but dont know if I will have the same results and dont want to waste money on shipping and the higher costs of these fish if there is an issue with my tank. My chemistry values are "normal" aside from the high temp. All nitrogen compounds = 0.00, pH = 6.8 avg, and GH/KH are 7/3. I have shrimp in the tank as well, which are doing well.
Any assistance is welcome.
