Lost My Bristlenose

[flyboy12]

Gday from downunder. I have lost 4 Bristlenose in a 4 week period. my tank finnished cycling at the time i brought the first one, i perchased them from two differant shops, I have ownd them in the past and found that they were a hardy little critter, I also have in the tank a sailfin pleco and a clown pleco and am woried that they will be next. The only sighn of any ilness that i could see was that the last one to go had a bright red spot on his belly. my water parameter is as follows.
150 ltr tank
dgh 3.4
dkh 6.7
ph 7.0
nitrite0.0
nitrate 40.0
amonia 0.0
temp 28.5 c

Sounds like the last one had an internal bacterial problem, and this was maybe what they all came with from the lfs.

The temperature is a tad high for BNs IMO but I don't think that would have killed them.

edit: How small were the BNs? A lot of shops sell BNs when they're tiny and when they're that small they're very sensitive.

two of them were about 3/4 inch which is small but the other 2 were adults, the one with the red sore was an adult. I am trying to lower the temp but its hard as the room gets fairly warm during the day
