Pregnant cichled gets throat eaten

[Tj203]

So I have a 600 gallon mix cichled tank. The fish have been breding like crazy but in the last 2 weeks I have lost 3 pregnant fish and when I find them they have there throat eaten and nothing else. The only think that I have changed is the feeding, I have cut back because they are getting older so I went from 3 heavy feeding to 1 to 2 light ones. I am going to try and feed more to see if that helps but I also wanted to see if anyone has ever had this happen before.

The tank parameters are great nitrates are under 10ppm
gh,kh are 10
ph 8.11
Water is very stable

What kinds of cichlids are in there?
Increased feeding may help, but it sounds like there is a really aggressive male that needs to go.

My guess is that one or some of the fish are trying to get to the fry in the holding females mouths and they were resisting.

You do have quite a mix of cichlids in that 600G tank so it may be difficult to figure out who it was.

Yea, I bought more rock so I can give them more hidden places. It dose always happen over night. I dont turn the lights off but it is a low blue light. I have 80 plus fry that can survive in the tank and I think it is much higher then that because I see new fry somewhere just about every day. I hope that now that I started to feed them more and when I get the new rocks I can stop this. I know some fish almost stay pregnant they spit the fry and a few weeks later they have more fry. They has to be weak because of lack of food. This size tank help because I know I have fish that should not be together depending on who you ask and I don't see much more then some chases. Once a while some lip locking but that is like once a month if that. Here are some pictures anyone have a good way of cleaning the bottom 8 inches of the tank? Bought Snails it worked until the fish ate them lol. I have 3 plecos in there i want more I want 1 or 2 more then grow very big but I can't get it clean with the stick dose not work and the mag flote scratch the tank.

Very pretty tank & quite a mixed bag of species. Really no way to solve the murder mystery unless you catch the perpetrator in the act.
Consider adding a group of Red Tail Loaches (Y. Modesta). They are tough Botias & great scavengers. Red Tails do a good job keeping the bottom clean.

Beautiful cichlids and tank! I’d love to see a full tank video!
If I had to guess, I would say the killer would be a jewel, Texas, jack, or Vieja, just for aggression potential. Hard to truly say for sure though. Like A201 said, the only way to really know who did it is to watch them in the act.

I just need the glass cleaned i have 15 geo's maybe more to keep the sand clean. The tank is about 10 months old and I have never vacuum the sand and for 6 months or so I have only added water. But keeping the acrylic clean is too hard I need something better then me just using a pad and doing by hand. The problem i run in to is the stuff is so hard to get off so I need to use a lot of force to get it off and I can't get to the bottom off the tank and put the force that is needed.

A couple of BN plecos may help with the algae.

Here you go some videos of feeding time and just some fish. It's interesting that you would say a jewel all the jewels I have are very timid And just stay to themselves. So crazy how different different a fish from tank to tank.
