DiscusLover Posted June 15, 2022 Share Posted June 15, 2022 I woke up this morning to find 3 of my albino corys dead with red marks like this one and I am not sure what happened there was no ammonia spike and nitrates were low 2 Link to comment Share on other sites More sharing options...
Colu Posted June 16, 2022 Share Posted June 16, 2022 It looks like they have injured themselves is there anything in the tank that come have injured them other aggressive fish that could have killed them or some ware they could have be trapped or got into a tight space Link to comment Share on other sites More sharing options...
DiscusLover Posted June 16, 2022 Author Share Posted June 16, 2022 No I do not have any aggressive fish but I do have pipes inside. But it never injured any of the corys until they started acting weirdly a week ago Link to comment Share on other sites More sharing options...
nabokovfan87 Posted June 16, 2022 Share Posted June 16, 2022 Are they flashing at all? What do you mean by "acting weird"? Please show the scape in the tank so we can see what they may have hit if anything, or narrow that out as a factor. Do they go inside any decorations?

DiscusLover Posted June 16, 2022 Author Share Posted June 16, 2022 Im not sure what you mean by flashing. Last week I introduced 3 baby blue acura and 6 baby angels and it was going well for a couple days and then I noticed their behavior changing they were less active and eating less then they used too. All the other fish were doing okay Im not sure why it was only cory. The only decorations that I have seen them going into is the pipes but rarely and under the rock but other then that they are out in the open and in the plant area and for the wave maker I turn it on for a min after they are done eating so that the leftover food and poo gets into the filter Link to comment Share on other sites More sharing options...
