No thrashing, but an observation. Oleg Kiselev once advised me that 
there is no such thing as too many water changes.

I agree BUT!!!

If the fish show agitation after a change, or stop laying eggs, suspect 
something is in the water they do not like. In rural areas it may be 
nitrates or ammonia, even chloramine, at very low levels from 
agricultural fertilizers. 5 parts per billion of ammonia will stunt 
babies and damage gills. Not much more can reduce fertility 
significantly. 100 ppb of chloramine is likely more than enough to 
permanently sterilize West Africans.

These are values most test kits don't even recognize, so use some 
caution. Try a few drops of Amquel o/e with water changes.
