Anti-jump devices and fish catching devices

Ok, so I have tried a couple of anti-jump devices so far and I do not like them. First I had the glass top, now I just tried eggcrate. My complaint with both is that they cut down on too much light especially the egg crate.

Does anyone else have any suggestions? I really want another to keep another Flasher Wrasse, or some other jumpers, but do not want to get them until I can make sure they are not going to jump out.


2nd, if I have a clown in my tank that I would like to get out without taking apart my rock stack, what is the best way to get him out? He has turned pretty aggressive, and I want to keep some smaller fish that he may terrorize.

Thanks
Dale
 
try either purchesing a trap or simply making one yur self ;) as far as anti jump devices the glass top is probally the most effective but id stick with the eggcrate since the glass traps in the heat... btw the eggcrate doesnt really blockout as much light as youd think

That should be added to the myth thread. In actuality some suggest the eggcrate may increase the light by tunneling it more.
I dont agree-but anyways it certainly does not decrease the output much atr all.
 
Well, it may be a myth, but I see darker spots in my tank especially in places that the light is not directly over...Is that just an optical illusion?
 
Light travels in a straight line. If there is a physical object in the way (egg crate) that light will be partially of fully reflected or absorbed. So egg crate will

absorbs the light aka blocks the light from getting in the tank

and reflects it into a new direction. which may be towards the tank or back upwards.

So you will loose some light to absorption and some to reflection.

Its the physics of light. The further you get away from the light the more material you will have between the light and water. To demonstrate this take some egg crate and look through it. Then slowly tilt it so that you go from a top view to a angled one. The depth of the egg-crate starts to become more visible and blocks more light.
 
Dale, In my case I was able to use some silicone netting material use as a antislip in bars. I used this material to enclose the fishtank outer edges and any other gap there was on top without going under the lights as the lights fixture itself was a barrier already.
this may or not work for you depending on your set up.

Clowns are hard to catch with trap or with out, I have had good luck with fishing line and iny fly hooks, I found this hooks in bass pro shops and they a tiny. have a container ready for him and Just bait the hook and put it close to him the rest is the same as fishing :D

good luck

LOL as u noticed I stated that it does not decrease the PAR as much as originally thought. U may very well see some reduction .
BTW what light are u running?
A tight canopy should do.\I have tons of jumpers(purple tilefish-wrasses(many) firefish etc. Just have eggcrate over my overflows and a tight canopy.
 
I have the current 4x39 t5 fixture. Unfortunately, because of this I cannot afford to loose any light. :) Because my tank is in the book shelf some of the other options wont fit.
I dont have a canopy per se, I guess an option would be to use wedges of sort between the bookshelf walls and the tank. Then have a front piece of wood so that it does not decide to get out that way.
 
Try catching the clown in the early mourning or a few hrs after the lights go out. usually mine are dead asleep and i can just stick the net in because they wake up dazed and have no clue whats going on. i can even catch then with my hands.

Sounds like a plan, I will try that :)
 
I was gonna suggest the same thing as ek9vboi cause my clown sleeps at the top of the tank at the overflow, and sleeps like it's his business. I have to shine a bright light in his eyes to wake him up at night, whereas with my sailfin, as soon as any light hits the tank, whether it's surrounding lighting or direct light looking in the nooks and crannies of the tank (or checking PE on the SPS), he's up at the first shine, jumping in front of the light constantly.
 
This is a great topic. I just lost my diamond goby :( because he jumped out in the night. I cant understand how he jumped out, I had a lid placed on my tank.
 
I just found this about eggcrate:

It's A. Calfo talking about covering your reef top with eggcrate. He doesn't discuss the ammount of light reduction that occurs, but he refers to that as "they block little light from above."

Also he says to remember to have the tapered (sharp) end facing upward, with the flat end down. That way it allows the light to focus. The opposite way is to diffuse the light.

Rogger, that is a great idea for the outer edges, I will give that a shot. For the clown, well i guess its fishin time...Thanks for that suggestion.

As both you and Bawla pointed out, I will make sure I have tapered side up.. If that does not work, i will go with Roggers suggestion.
 
try catching the clown late at night when the light have been out and the tank in darkness for several hours. i find my clown sleeping in the corner of the sand bed when i use a flashlight on sleepness nights to check polyp extension. i've always thought i could easily catch him.
 
i think the egg crate will block light depending on your light source. if you are using floricent or t5 lighting it won't block much, however if you are using MH it will block light especially in the far corners of the tank. it's the same principle of what we use in xray generation to block any non parallel light rays. that is why they use it on that type of office lights.
