I got 12 orange finned danios at the weekend to go in my 180 litre tank that has a juwel filter. Since then 4 of them have died after getting stuck in there. And there are currently 4 in there now that I cannot get out. This morning after we found the dead ones we blocked the intakes with some filter floss, apart from the one round the back in between the filter and the glassglass, and the filter is siloconed in place so it can't be moved. Then I just found 4 (alive) danios in there, so as I can't get them out the filter has been turned off and all media removed and put in bucket of tank water. The heater has also been removed from the slot inside the filter and put in the main tank. I suspect that they are squeezing in between the glass and the filter and getting in that way, but it could be the front. Is there anyway to block off the back filter inlet? We ordered the juwel shrimp guard for the front sections. I really think that juwel should add this into the filter itself and make sure that the gap in between the glass and filter is thinner as when my keyhole cichlids were younger they could get round the back too, just wondering do you think I should complain? Thanks in advance, also sorry if this makes no sense, it's quite dark at the minute.
