a couple of weeks ago i took rainbow (female guppy) out of the main tank and put her in a small fish bowl so that when she had some fry the other fish couldnt eat them i was starting to wonder whether she was going to have any ,but the next morning when i woke up she had had some fry i took her out and put her in a jug (cause there was that many i had to take her out ) i counted them and there was 21 fry , but the funny thing was that they normally eat there fry but they were swimming next to her and she didnt touch them in the end she had 37 fry i was very happy with her because i have never had that many guppy fry in one go.
