How can I jump-proof my tank?

[rsanz]

I have a new pair of Gold Lyretail Killifish coming this weekend, and I know that they are characterized as jumpers. Now, two questions:

1. I have hanging filter and heater that I had to punch holes in the tank cover to allow them to hang on the back of the tank. Should I be worried about these holes?

2. What should I do when I need to change the water? I need to take the lid off to do this, but how can I prevent them from jumping out?

Thanks in advance for your help!

just make sure you have most openings closed, they will not look for a spot to jump and try to shoot through it.

As long as the holes are relatively tight to their respective equipment, I wouldn't worry much. Jumping is a problem but the fish don't generally aim on purpose for that one tiny little spot where they just might fit through if they really really try with serious precision. :joke:

To do water changes without having to open the lids, you could create a sort of flap thing. If the tank top has that flexible plastic in the back, you can cut it into an closeable flap. Just open it, stick the tube in, syphon away, and the close it. Repeat to introduce the new water.

If you are super worried then get some sort of plastic mesh screen and place it over openings. I use a completely open topped tank as I want to keep the temp as low as possible in my setup. Never had a fish jump yet.

Fish will usually jump for 2 reasons - environmental (temp too high, old water etc...) or to get food. A rare fish will also want to migrate.

TKOS reminds me - light grid / egg crate is an excellent way to cover a tank if you want it to be somewhat open but also relatively jump-proof.

You will be fine. They jump when they get spooked. I have a school of about 10 killies and they do not jump at all (except when I brought them home from the store)
