I've been having a string of no-good-very-bad-rotten luck this week with fish illnesses. First I had to euthanize my favorite betta when I discovered that he had dropsy (long story, will never leave fish in my parents' care for an extended amount of time ever, ever, again).
Now, one of the pygmy hatchetfish in my 12 gallon planted community tank looks like he might have ich! There are little white dots on his fins, and some of his caudal fin looks a little ragged. If anyone could confirm this diagnosis, it would be much appreciated. I'd also like some advice on how to medicate for this condition, and whether or not I should treat the whole tank. I recently found out that hatchets are prone to ich, but also cannot tolerate strong doses of malachite green, which seems to be in all of the invert-safe ich meds out there. I have some ParaGuard at home, which has a low dose of malachite green mixed with formalin in in, but I'm a little concerned about using it.
Any help is greatly appreciated!
Appearance Changes: White spots on fins
Behavior Changes: None noticed
Eating Habits: Still eating regularly
WATER STATS (Will post later when I can finish tests)
Hardness: kH(7*), gH (7*- 8*)
Time you noticed the illness:
Size: 12 gallon Aquapod planted community
(Note: My tank yay have a touch of NTS... I thought the cycle was good and done, especially since I was using a butt-load of previously used ceramic media with a well-established bacteria colony in it, but I may have thrown things out of whack when I stocked it)
Filtration/Aeration: stock Aquapod filter (roughly 160 GPH)
Frequency of Tank Cleaning: 20-25% WC every other week
Water Additives: Prime, Flourish, CO2 (from Nutrafin CO2 System)
Feeding (food type/frequency): SERA Tropical Fish flakes 1x daily, skip feeding on weekends. Fed frozen daphnia and bloodworms once or twice a week.
Tank Mates: Hatchetfish in question is part of school with 5 others, also 6 harlequin rasboras & 3 pgymy cories (will get more cories soon). All fish are recent additions to this tank. Both the rasboras and the pygmy hatchets came from the same tank at my LFS, and my cory shoal comes from an older tank that I broke down. All fish were quarantined prior to introduction.
Any treatment so far and when: Currently raising the tank temp to 86*F.
List any past health problems: None known. Fish are recent addition to tank.
Here is a video with the fish in question in it:
