Longnose hawkfish driving me crazy !!
 

My longnose hawkfish keeps getting into the overflow box (drilled 65gal tank) and it happened last night and again this morning... Its such a pain to get him out each time, any suggestions on DIY'ing something to keep him out but not alter the flow rate ?

Thanks !

You can try putting him in MY tank:wink: That would for sure keep him out of YOUR overflow box:biggrin:

Seriously, eggcrate the top of your overflow.

I've seen your tank, compared to mine its HUGE !!! My hawkfish would love it. My wife although, would hate me forever as she's named him Mr.Bojangles and is her 2nd favorite fish right behind her Bi color Blenny. Anyone got any pics of the egg crate idea ? Just use silicone to hold it in place ? Can you get it in black ?

enclosing overflow top
 

i can assure you this works just fine. i've had so many snails, hermits and even clownfish tumbling into overflow that i ended up enclosing overflowtop with eggcrate. i cut eggcrate a little larger than overflow circumferance and placed a glassblock ontop to hold it down.

I thought SeaHorse was referring to building up the wall with eggcrate, I guess enclosing it would be easier but what if the when the fish jumps like I'm assuming it does to get back there then woudn't it die because it would be out of water ?

You can see a pic of my overflow with eggcrate here,

If you keep smaller fish that are curious like a longnose hawk they will usually find their way through eggcrate, the holes are just too big.
Here is a picture of the aquamedic overflow combs which are adjustable and well suited for your application. I ended up going with a one piece custom made acrylic comb instead but I suggest you look for something along this line instead of eggcrate.

From this next picture you can get an idea of how the comb styles work & look in my overflow.

I dont think the hawkfish is getting through the holes but I could be wrong. He's a fair size, I was assuming he was jumping over the top of the overflow.

My over flow is square on the top so I just cut an overly large square and placed it right on. Keep in mind this will increase the water height in your tank. Has worked well for me.
