Bear Posted December 3, 2021 Share Posted December 3, 2021 Story time: I had a thriving heavily planted aquarium with 7 corys, 2 otos, 25 olive nerites, 8 amanos, and an indeterminate number of RCS's for a little over a year. I had to leave for a work engagement for about a month and had a friend (who knows nothing about aquariums) feed the tank a tiny pinch sinking wafers every three days. Friend told me the tank was starting to grow algae pretty bad, but I said, "don't worry about it." My octopus plants apparently took over the tank. I returned to a tank with horribly fouled water, ALL of my RCS's gone, all but one olive nerite dead and fouling the water, algae out of control with tons of that weird foamy algae that grows from too much protein. The Amanos all happy and healthy--nice and chonky--and all of the fish alive and healthy looking though hiding much more than usual. I'm still finding empty snail shells every once in a while after three weeks trying to recover my tank. My vals, java ferns, and amazon sword died from being covered in a film of algae. Crypts, octopus, dwarf sag, dwarf lily fine though disappointed in being neglected. The java moss died where I placed it and grew onto the log in the tank. Tank parameters: 60 gal; "hot rodded" HOB; airstone; bubble bio MB filter 75°F 7.3pH 0ppm NH3 0ppm N02 10ppm N03 0ppm Cu 10 dGH 10 dKH For an entire year the inverts in my tank have kept it great shape sometimes a little too much poop but nothing that was a problem. I had read that sometime neocardinias get some kind of black rot (from overcrowding, I think) that is very contagious amongst themselves and nearly 100% fatal if not dealt with. I took a sample of my water to the local aquarist shop to have them test to see if the water conditions were borked. They said the pH was a little high but nothing too bad. So I bought 30 more RCS's. Within a week, all gone, no corpses, no reds. I tested the water again with roughly the same result as above (I think the hardnesses varied slightly). I'm still battling the algae that grew on everything but the water remained clear and it is slowly getting back to being nice to look at. However, I'm very disheartened and on the verge of scooping up fish and amanos and re-doing the entire tank. TL;DR Did my corys get starved while I was away and have a taste of shrimp and that's what they want to eat now? Why did all of my inverts except Amanos, and one olive nerite die, but the fish are fine? Thanks for sticking through the story. 1 Link to comment Share on other sites More sharing options...
