I have had 5 caves in with 11 adults up until this weekend. Sadly I had a male trap a female in the round cave and she died in there. So now I am down to 4 caves as I removed the round one. I have had aprox 10 spawns now with an average of about 25 per batch. One particular male has not been without a spawn the whole summer and at one time had wigglers and a new clutch of eggs at the same time.In one of the posts above, you said you had 5 caves, then bought some more, how many fish did you have in the tank to caves when they finally bred for the first time. I have loads of caves in my tanks, and possibally think I may have too many.
The lack of cave competiting maybe my problem.
I have only one cave per male but have lots of hiding places for the females in amongst all the wood.mmm Very interesting, That what I have been told to only have 1 cave per male, although I have also been told to have more caves than fish (To an extent) i.e. 3 caves per pair.
