Fish ending up in Sump??

[E_rock]

Hi everyone. Weird question to ask everyone. My 90 gallon tank just finished its cycle. And I went down to the fish place yesterday. And I got 3 chromis, the manager there told me they actually came for the niagara falls aquarium and there pretty large. And this morning I went to feed them, long story short. None of them came up to eat, and for that matter I couldn't find them. After checking the floor and behind the tank. I looked in my overflow and my sump. And there I found two of the chromis in the filter sock, chowing down on the food, by that time got sucked down there. I released them back into the DT they seem to be alright. But I feel lucky I found them there within a few hours. And I later found the third. But I dont know whats causing them to make it down to the sump. I am using the "herbie" meathod. (i think, The one with two drains and one is restricted) for the overflow. Any ideas about whats causing this or what i could do? Thanks I just dont want to chop up my fish in my return pump.

Could you take a picture of your overflow for us?

If you are using a filter sock you won't have to worry about them ever getting chopped up. I have found several of the smaller fish I've had over the years in the sock. I think they like the ride down, kinda like a water slide.

I have a flame hawk that has been living in my overflow for 1yr now. I can't get him out and he won't jump back into the DT. I feel bad having him in there but he doesn't seem to mind.

Grab some "gutter guard" from a home improvement store, cut to fit the top of your overflow=no more wild rides to the sump.

gutter guard...good idea sorry I havent been able to put up a picture. Crazy day. But I feel bad cause one of my chromis got kind of beat up on the ride down.

I am using a mag 12(apx 1200gph) Could my return pump be causing it?

Heres some pictures, i turned the flow down on my pump. If it happens again i will try the gutter

The flow on your pump isn't a factor. The fish are jumping into the overflow, not being swept into it. You need to block access to it or this will most likely happen again.

Good luck!
