Other Required Info:
Brand of test-kit used and whether strips or drops? I used API brand test strips
Water temperature? 76 degrees F, heater regulated
Tank size (how many gals.) and how long has it been running? 40 gal breeder, 3 years running
What is the name and "size of the filter"(s)? Aquaclear 50, plus a 6" sponge filter
How often do you change the water and how much? once per week, about 45% change (18 gallons)
How many days ago was the last water change and how much did you change? changed water today (5/08), did standard 18 gallon change.
How many fish in the tank and their size? For about 1 year I had 2 juvenile bristlenose plecos and 2 mature (7" and 8") oranda goldfish. The plecos were removed about 4 weeks ago, so now it just has the 2 goldies.
What kind of water additives or conditioners? I use Seachem Prime conditioner, occasionally add aquarium salt at half dose (4-5 Tbsp/40 gal) therapeutically after wen trimmings.
What do you feed your fish and how often? Tank is fed 2x/day, they get a rotating variety of: Bug Bites Pleco Formula, Bug Bites Goldfish Formula, New Life Spectrum Cichlid Formula, very infrequently they get Fresh Frozen Brine Shrimp and Fresh Frozen Blood worms (leftovers from feeding my betta). There are also plants in the tank that the fish nibble on, and I give them bits of vegetables to nibble on.
Any new fish added to the tank? No
Any medications added to the tank? No, not recently, see below.
List entire medication/treatment history for fish and tank.Please include salt, Prazi, PP, etc and the approximate time and duration of treatment.
The only medication the tank has received was in its first year of running, one fish suffered an anchor worm infection. Visible parasites were manually removed, fish treated with salt dip. Treated tank and fish with ParaGuard per instructions (5mL/40 gal, repeated daily for 3 days), and Microbe-Lift Lice & Anchor Worm treatment (1 tsp/20 gal, provided 1 treatment). After treatment the tank was given a complete decontamination with 100% water change, wash out and treatment with hydrogen peroxide. Fish were replaced in tank and have shown no signs of parasites for over 2 years.
Any unusual findings on the fish such as "grains of salt," bloody streaks, frayed fins or fungus? The affected fish shows some pronounced caudal fin ray arteries, and 2 small spots of fin tip damage (bloody, irritated looking) on the caudal fin.
Any unusual behavior like staying at the bottom, not eating, etc.? Affected fish struggles to maintain body position in the water. Head sinks the whole fish to the bottom (as seen in the included picture) and then flips him upside down when he tries to rest. His wen is disproportionately large compared to the rest of his body and affects his eyesight and feeding (he cannot see his food, he relies on chancing upon it once it sinks to the bottom of the tank). Despite his struggles, he actively swims as best as he can and has had no loss in appetite.
Hope this helps!
