What's peoples thoughts on open top tanks! I've had a jumper today and gutted! This was in my Superfish scaper 60 and the jumper was a lemon tetra. I'm planning a much bigger tank and really want to go open top but now worried about jumpers. I just think the open top tanks look so much nicer! I guess I could run the water lower but I just think that takes away part of the aesthetics too. Obviously livestock is the primary concern here so maybe a glass cover?
 
It’s always a risk in open top, things that can help is stocking choice, lid, floating plants, water level height. That’s all I can think of at the moment 🙂
Yeah have some floaters which I thinned out a bit as they were completely blocking the light and I was running the water a bit high! Lessons learnt!
 
Keep the water line down an inch or 2,if I fill it to close to the top I get the occasional one jumping out,it will happen from time to time with open top tanks
 
If you have an open top tank at some point you will have jumpers, it’s inevitable unfortunately. Ensure you have a light that doesn’t just turn on and off and has a ramp down feature. I’ve found a lot of fish will dart about with the sudden change in light levels.

Also some species are just prone to jumping. For example wild bettas will look for gaps even in covered tanks. Another that’s notorious are rope fish, they’ll find the tiniest gaps to escape through.

Thanks
