I have looked around on the old interweb and can't seem to pinpoint whats going on. These spots came up about 2 weeks ago after a few deaths in the tank. I had 3 gouramis die within 3 weeks, I found out that the crab was attacking them. One of the gouramis went missing, the crab was eating it and hid it in the log. This spiked my ammonia and the tank hasn't been right since. The other 2 gouramis got sick after and were quarantined but still died. The crab just died for no apparent reason about a week after. The smaller one has more spots than the other. Today the smaller one has developed a red spot that is not pictured, I think one of the spots may have popped.
ph-7.0ish, ammonia-.1, nitrate-0, nitrite-0, kh-100, gh-60. My water is a little too hard, but it has been like that for several months. I used the api test kit with the chemicals not the test strips. So my numbers may be a bit off because of color judgement.
I have done a 40% water change every weekend since this happened and a 10% change every other day. I added 1tbsp of aquarium salt at each 40% change. I also raised the tank temp from 79 to 82*f, I thought it may be ich. This freshwater tank has been going for around 8 months. 6 different tetras, 2 chinese algae eaters, 1 glass catfish, 1 snail. They haven't been quarantined yet. All live plants. Fluval U4 submersed filter with biomax and carbon inserts changed in rotation every week. I also have an air pump with 14" bubble wand. Natural sunlight gets on one side of the tank for around 3 hours if its sunny out. t5 UV light and t5 colormax is on for 16hours of daytime and the bubble wand has blue led for moonlight simulation. The fish get tetra flakes at 6pm every night, freeze dried blood worms every other night, tubifex worms once a week.
I hope this is enough information. Before I try any changes or treatment I want some "expert" opinions about whats going on. Because a picture is worth a thousand words, I attached a couple pictures of the tetras.
