Ok first. 10g tank. Originally held one young male betta (grew up in this tank) "Baby" with an albino corycat named Napoleon. Over time the tank came to hold an albino bristlenose pleco, 2 zebro danios and 2 longfins, 2emerald corys and a zebra cory. All coexisted great, no aggression though the female longfin is not a good schooling fish (she chases everyone away) no one has shown any distress and all eat great. This was an extremely healthy and established tank. About a month and a half possibly two months ago, i added the 2 golden loaches. Other than being a bit invasive to personal space, they dont bother anybody and didnt cause stress to the ecosystem of the tank. I do consistent tank maintenece and chem tests. The water is a bit on the hard side from us using treated well water (sorry not sure of numbers) but nothing dangerous and this tank has never had an ammonia spike,ph problems, or issues with cloramines nitrate or nitrite. Every so often ill get a small algae bloom from high phosphate levels? But a dose of bacteria culture and low lighting always clears it up within a few days. Since adding the loaches i have been more causious with chem treatments since they can be more sensative to abrupt change. However my corys seem to get sickly when the blooms occur so i always try to treat as quick as possible. We went on vacation for just over a week and came back (june22nd) to Baby and an emerald dead. The loaches were also puffed up. They are not showing obvious distress. Nothing is out if the ordinary except their appearence. They have a soft tissue on their backs along their spine that looks inflated. No sores or discoloration, no drowsyness or lethargy. Ive treated for parasites,bacteria,and fungal with no change. All other fish were in good habits until the second emerald died yesterday early morning. Ill take pictures when i get home. Also,theres another algae bloom but im scared to overdose the fish woth treatments.
