Lost a few babies last night (5), cleaned the filter out on Monday and neglected to check the water, ended up doing a 80% water change on Wednesday night as the nitrite had gone through the roof! All seems back in order now though and they are quite happy and starting to bulk out! Feeding a pinch of tetra prima in the mornings, the same in the evening when i get home and i sneek down before i go to bed around midnight and do another pinch.
Really strange size comparissons at the moment, i've got a couple of massive babies while a few still seem to be like 4 week old size still. I've added a powerhead from my old tank to get some extra flow going in there, i've noticed a few of the youngsters have a bit of a kink in their bodies just before the tail fin. I think this is a typical spinal deformity of corys that are tank bred. Out of the 200 i have, there are probably 10 like this.
I've got the temp set to 22 degrees which is just slightly warmer than my tap water and i'm doing a 80% water change every other day using a hose, which makes it much much easier.
