Fish Symptoms (include full description including lesion, color, location, fish behavior):
--The first fish to die was one of my sunset blushing angelfish and one of my tiger barbs. Neither had been displaying any unusual behavior, they were both floating on Sunday morning. Neither showed any indications of disease (i.e. no discoloration, bloating, spots, etc.), nor was there any visible trauma.
--Next was an albino bristlenose pleco. I hadn't seen it for a couple days, then found it floating Tuesday morning. It had white scaly patches over roughly 1/2 of its body, one of its eyes looked to have an opaque white covering over it, and its abdomen had turned dark blue/black.
--This morning, I found the new regular bristlenose pleco dead. Its fins were a little ragged along the edges, but other than that, it looked like it had when I bought it on Saturday.
--This evening, one of the odessa barbs died. Again, like all the other fish except the albino pleco, it showed no disease or trauma.
Volume and Frequency of water changes:
--45 gallon tank, 25% change every two weeks
Chemical Additives or Media in your tank:
--Only chemical additive is the dechlorinator that I put in when I do water changes.
Tank inhabitants:
--Before the dying started, I had the two bristlenose plecos, seven tiger barbs, four odessa barbs, two sunset blushing angelfish, three clown loaches, and a rainbow shark.
Recent additions to your tank (living or decoration):
--The regular bristlenose pleco is the only new addition. Everything else in the tank has been there for around two months. The tank itself has been in use at my house for about two years, but around Christmas, a bout of ick wiped out everything in it (HUGE loss, three clown loaches that were 5+ years old, a 15+ year old common pleco, and a 3 year old angelicus loach). At that time, since the tank was empty, I removed all the big rocks and vacuumed the whole thing out before putting new fish in.
--I was concerned that the population was too big for the existing filtration (a Fluval 205), so when I got the new fish population, I added a Penguin 150. With the two of them running, the chemistry's been stable, and I've not seen ammonia go above 0.
Exposure to chemicals:
--None
Feeding:
--Sinking cichlid pellets in the morning, and a cube of frozen bloodworms in the evenings. Some evenings, if the fish look like they're hungry (i.e. swarm over to the edge of the tank and follow me around when I come in the room), I'll give them some pellets before bed.
I'm feeling rather desperate at this point. It was bad enough the first time around, but at least then I could see what was killing everything. Now, the fish are just dying, and I can't figure out what to do.
