Ugh...I guess I should start with the basic info about the tank setup. -10 Gallon (US) tank -Whisper 10 Filter -12" Air Stone w/10-15 Gallon Air Pump -Lighting: Flourescent, on for ten hours a day with natural light the rest of the time. -Gravel Substrate -1 Male Dalmatian Veil Tail Betta -1 Pleco -1 African Dwarf Frog -4 Ghost Shrimp -Mondo Grass -Up and running for two and a half months -pH: 7.2 -Ammonia: 0.0ppm -Nitrites: 0ppm -Nitrates: 5ppm -Temperature: Adjustable heater, normally 78 deg. F, currently 84-86 deg F due to illness(es) -Water Hardness: No idea, but hard. -Additives: Nutrafin Aqua Plus conditioner, Aqueon Aquarium Plant Food, API Aquarium Salt (3 rounded tablespoons for the entire 10 US Gallon Tank since the ich started). -Diet: Rotation every couple of days between Omega One Freshwater Flakes and Betta Min Tropical Medley. The betta completey stopped eating pellets after introduction of the Tropical Medley, but whatever makes him happy. Twice a week, I feed the betta and frog some freeze dried bloodworms. Once a week, I fast for a day, followed by one blanched and smashed pea for the betta to avoid constipation. Here's a breakdown of what I've been dealing with: Idiot me has been out of the swing of aquariums for a few years and made a n00b mistake. I brought home a beautiful Blue Ram Cichlid from LFS and did not quarantine him. (Lesson learned, purchasing quarantine aquarium soon.) Of course, he sparked an outbreak of ich. Flashing, white spots, the works. The normally hyperactive, happy, and hungry betta was not eating, hiding almost all the time, or hanging out on the bottom. His color began to fade as well (He was very, very pale when I brought him home, then turned a deep red after a few days). The pleco seemed completely unaffected, the ghost shrimp had ich but were still behaving normally, and the poor frog had no spots but seemed very stressed. The tetras, covered with ich spots, were still eating and schooling, but began dying off one by one. The catfish showed no signs of ich. Before the first round of Nox-Ich was complete (3 days of .5 drops per gallon given the ghost shrimp, African Dwarf Frog, and the 5, now 0 neon tetras, carbon filter removed of course), the Blue Ram, neon tetras, and catfish were dead. During this time, the betta developed the appearance of fin rot, most likely from flashing and hanging out on the bottom/hiding. And his fins were so long, flowing, and beautiful! I have seriously never seen a veil tail with fins like that in person before After 24 hours, I did a 50% water change with an overall gravel vacuum and resumed treatment the next day with the ich still present. Another three days of treatment and another water change, and ye olde ich was still there. The aquarium guru friend of mine suggested five days of .5 drops per US gallon followed by 24 hours of no treatment, then a 50% water change. So, that's what I did. The betta's fins started looking ragged... really ragged. After the third round of Nox-Ich, the ich was completely gone. The spots disappeared two days in, so I'm assuming that the free floaters were most likely killed off by the end of the five day treatment. The betta's fins stopped deteriorating. He began eating during the second treatment, was swimming around a little more, and was no longer hiding or flashing. However... yesterday, I noticed some algae like growth on the top of his head, his tail fin, and one pectoral fin. It was a greenish-gray color and looked like algae. Currently, I cannot see any on him at all. He does have a spot (not ich-like), approximately 1mm in diameter on his side. It just looked slightly pale compared to the rest of him. It is located on his left side, just superior and posterior to his pectoral fin. I have pictures, but it doesn't show up very well. Today was post-treatment water change day. Just prior to the water change, I saw the betta flash again. He also swims up against the mondo grass, but just grazes it as he swims by without flashing. F.M.L. There are no white spots on anything in the tank, but I'm assuming I should do at least a three day Nox-Ich treatment as a precautionary measure. Questions: 1. Is it normal for ich to be this persistent? 2. Could today's flashing be the result of something other than ich? 3. Any clues on what the algae like growth and pale spot could be (bacterial, fungal, etc)? 4. If the algae like growth and pale spot on the betta are fungal, is there a way I can get rid of it without annihilating my beloved nitrogen cycle? 5. Will the betta's fins grow back? I have attached a few pictures of the betta, but there is no algae like growth currently present and the pale spot isn't terribly apparent in the photos. My apologies for the picture quality... he was swimming around a lot and I was using a Droid X 2. I apologize for the novel as well, but I wanted to include as much information as possible.
