jumping gobies

Nassarius snails maybe? Great sandsifters

 

+1 on Nassarius snails. I had a diamond goby and lost him due to his propensity to jump (ended up trapped in the filter sock of my sump). Got some nassarius snails and now the sand bed is clean.

 

if your rock is precariously stacked then i would reenforced it or make is so that it has no chance of falling, a good way to test this is to do the tap test by acting like a big fish and tapping fairly hardly on each rock in different areas so that they have no chance of falling.

it doesnt take much for a rock to fall and completly blow out the tank.

just a word of warning

 

Thanks for the plug, Robman. I have no idea if I did this right - trying to show the link to that thread.

The night top continues to work well. So far, everything is staying in the tank (at least at night).

 

very professional looking. i wonder. do most jumps occur at night? it would be no trouble to toss something like that on there when i go to bed. i just wouldn't want that on all of the time.

 

Both of my jumpers were at night - may be coincidence only, but my feeling is that they got spooked. We're working on a canopy now to prevent future jumpings - day or night!

 

I think a lot of jumping happens as the lights go off unless you have a dimming light as your "sunrise/sunset". Most fish go to sleep once the lights are out so there's a pretty narrow window between awake and swimming and asleep for the night where I'm guessing a lot of jumping happens. For most people the lights going out completely is a sudden event.
If you wanted to get something on as a preventative measure I think you would need to get it on before the lights go out every night to be safe.

There is another solution using a regular DIY screen frame kit but instead of using actual screen use 1/4" or 1/2" pond netting. It doesn't block much light, and is pretty low profile, but not perfect, if you're going for rimless. But if you want a perfectly rimless setup I think you pretty much have to accept that jumpy fish are going to jump and either stock non-jumpy fish or accept the loss of jumpy fish.

Even if most jumping happens at one particular time or another there is still no guarantee that they won't get spooked during the day and hop out at their convenience (your inconvenience).

 

my sand shifter has never bothered anything else in the tank; but he will disappear for days at a time. he does keep the tank nice, unless you get cyno then he try to crawl up the sides. he'll also do this if your water parameters are off. the thing is he eats copodes and other benificals and can quickly starve to death if he runs out. I have a 35gal 50 gal. and a 75 gal. he gets some time in each tank. I change him around when ever I see him top side to much.

 

yeah, ive been doing a little reading and i dont think i have a suitable tank for the sand sifter (as cool as he is). my footprint is way too small and the tank hasnt been up for even a year. maybe nassarius snails are the way to go.

ive already got two, how many do you think one would need for a 50G tall?
