Hello Anita.I had a similar experience with fish hanging out near the surface recently, only with no fish loss. This occured in a tank with a heavy fish load. the fish seemed stressed early in the morning and hung near surface before the lights came on, in a planted tank. After the lights came on and the plants started producing O2 and consuming CO2 things were fine. I added aeration. Problem solved.

I'm looking forward to the October meeting with bated breath, though.Though I am a newbie, I've already acquired 6 tanks, & have 3 really set up, & 1 functioning as a quarantine tank. Nobody warned me this hobby was addictive.But I need help over something that has me completely puzzled. All my tanks are planted, & my first one, a 39 gallon, is mature, with no ammonia or nitrite showing up at all. I'm doing a 15% water change each week, which is keeping the nitrates really low. It is heavily planted, and I'm delivering CO2 with a homemade system that seems to be working well -- when I did a hardness & ph test, it showed CO2 in the optimal range. It is slightly acidic, about 6.8. I'm running a AquaClear 300 filter, but it was used and doesn't seem to be quite as efficient as another of the same model that I have on a smaller tank, but it's close. Everything I can test is spot on. There is a little too much algae, so I'm trying to work on that with learning appropriate feeding levels & getting algae eaters in there.So here's the problem. My fish are dying. They seem to go in groups, one breed at a time. At first it was either ich or velvet (I don't really know the difference, haven't seen them in person), which I treated with Maracyn on the advice of the Fish Store. I lost my 4 gold rams & 2 blue german rams, my silver hatchets, & my 3 younger Serpae tetras (my 4 adults are still fine). That was during the ich/velvet outbreak, which taught me the wisdom of quarantine tanks, and my 20 gallon is quarantining 2 adult angels, & a 3 gallon is now quarantining some penguins and chinese algae eaters.Then I lost my 4 marbled angels (about 1" long each). Then my 2 siamese algae eaters died (which isn't helping the algae situation, but it will almost a month before the new ones are out of quarantine). In the last 24 hours I've lost my six silver-tipped tetras & my six marbled hatchets. Right now I've got 5 bronze corys, 4 adult serpae tetras, a talking catfish, a bamboo shrimp, a few rainbow shrimp, & 2 ghost shrimps, plus 2 fiddler crabs. I'm not seeing any other fish in there.I cannot imagine what is going wrong! Any advice of what to do next, or what to look for next, would be appreciated.Anita JacobsonBTW, some fish gave a warning that they were sick (the silver hatchets & the angels both started hanging out at the surface instead of swimming around). Some fish obviously died from ich/velvet. But some, like my marble hatchets, gave no warning at all. Swimming around happily one night, every single one of them floating the next morning._______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
