Hey, everyone. I'm having issues with my tanks and I'm really hoping you guys could shed some insight on the problem.
Tank #1 is a 20 gallon community tank with two air-driven sponge filters on a 40 gallon pump. Had 6 corydoras, 8 endler's, 3 nerite snails and a bunch of neo. shrimp. For plants there is anacharis, java fern, java moss, pennywort, buce, and frogbit. It is moderate to heavily planted with black diamond substrate. Kept to ~76F with minor fluctuations between 75.5 and 79.5. I feed Hikari betta pellets, TetraMin tropical flakes, sinking wafers, frozen bloodworms and frozen brine shrimp both thawed in tank water. This tank is nearly two years old.
Tank #2 is a 10 gallon betta tank with neo. shrimp and two nerite snails. Has a marineland 15 gallon HOB filter with 1 marineland filter and the rest filled with lava rock. Planted with anacharis, pennywort, dwarf sword, and frogbit. Also moderate to heavily planted. Substrate is soil capped with pea gravel. Kept at ~78F with fluctuation between 76 and 81. This tank is almost a year old. I feed Hikari betta pellets, bloodworms and brine shrimp.
I have reduced my water changes in both tanks over about 4 months, but have kept doing tests. The plants were at just the right balance to have 0 ammonia, 0 nitrite and 0 nitrates. I would top off the tanks after testing every week and would still rinse the filters on schedule, rotating so I didn't rinse all of the media at the same time.
Tank #1 has had issues for about a month. My largest female cory started showing signs of illness by swimming sideways and struggling. She was quarantined and died within 24 hours. I did water tests and figured it must be a fluke. About a week after, another albino cory started showing the same symptoms and later died. On the albino cory I could look better for any external signs but saw none. No red spots, no bloating, no fuzzy spots, nothing. Just that they had both looked pale. I did a water change and removed some frogbit, in case it was preventing oxygenation. Started worrying that maybe I was underfeeding, so increased feeding. Couple days later, another cory had the same symptoms and lived a little longer in quarantine, but I think I had just caught it sooner. Did another, 50% water change and added salt to the tank. Yesterday, one of the endler's came down with symptoms. He is currently in quarantine and I will be euthanizing him tonight since he keeps getting worse. The shrimp seem completely fine and even had a recent boom.
Tank #2 I noticed yesterday morning during spot cleaning and topping off that the betta was looking a little plump. Decided to feed him a little less. Saw tonight that he is pineconing and staying at the bottom of the tank. Have drained the tank about 50% and added antibiotics to the water, but I don't have high hopes.
All of the tests on both tanks (ammonia, nitrites, nitrates, pH, kH, gh) are all great and have not fluctuated. These tanks are in different rooms and do not have any equipment or tools in common. What could be causing all of these issues??
