Killifish Jump!
All killifish jump. If yours haven’t yet you either have tight fitting lids, or you are not very observant!
To be fair non-annual killifish are the main jumpers of the killifish world but I have kept killifish long enough that I wouldn’t trust annuals to stay still; they jump too.
For edumaficational purposes, let’s look at this innocent looking Aphyosemion polli male. He looks like a calm chill fish. But is he?
His main tank is the far left tank. I found him in the middle tank the other day. I went, right! Caught him and moved him back and reduced the water level more to reduce the chances of this happening again.
Two days later, he was in the middle tank again! Moved him again and reduced water level further to what it is in the photo.
A day later, he was in the middle tank again 🙄
I couldn’t be bothered to move him straightaway. The following day he was in the far right tank! 😱
Keep your lids on kids! It will save you heartache if you are keeping killifish.
With me and this particular fish, since I don’t have any females of this species, he is not in my priority to try to breed list obviously. I keep forgetting to put the lids back on properly for some reason. Actually the subconscious reason might have been to have something silly happen in the fishroom, to act as a catalyst for me to remind people about killifish’s jumping ability.
Above is a true account from the KillieOrCory’s Fishroom, name of the accused have not been changed to protect their identity! He knows he is a jumper! 🤣
