Unknown death of juvenile mayan cichlid (please help diagnose)

  • We are currently upgrading MFK. thanks! -neo
heres a video of my tank and all three were healthy during recording let me know if you got any tips other than the obvious “get a bigger tank” lol

The video clearly illustrates the dominate Mayan showing aggression to the other fish with the chasing and posturing.

Also the lucky bamboo (dracena) should not have it's leaves submerged. The yellowing of one is showing signs of dying. They will also not survive for more than some months in fluoride treated water.

It's all good. My advice is to study the species in question, use the search feature here, read what members such as duanes duanes Rocksor Rocksor etc have to say about the diet, tank size limitations, etc, and pay attention to the small details. Understanding ones own personal limitations, and then having the conviction to live by those limitations is key in this hobby. Even a 75 gallon is a relatively small piece of real estate for a single adult 12" cichlid, let a lone a group, let alone a breeding pair. You have already seen what even a very small juvenile mayan can do when his aggression is turned on.

Thanks for this advice! I understand that I do have so much to learn. Are they able to live in a 10g while they are juvenile for short term then upgrade to larger as they grow?
 
Rocksor, you are right about the bamboo I already removed that one and was wondering why it died thanks for that info
 
From your first post saying they were small, I thought you might have time, but... as others have said, a 10 is already too small, they are already large enough for a 55 or 75 gal.
The largest has obviously decided it is only ig enough for it alone.
I kept mine in a 150 gal where they did well, but actually out grew it.
Your tank at the monent is only big enough for some guppies or neons, or something like that.
As far as adult or even semi adult cichlids go, maybe Rams or Apistos, the only Central American cichlid might be Amatitlania nanoluteus, and it would be pushing the envelope, for even 2 adults.

No. See above. The tighter the space, the more you will see aggression wise. Crash now owns the entire 10 gallons, and I suspect a 75 gallon would have the same end results. Do your homework amigo, most cichlids have anger issues. That should have been lesson 1 here.

Something to consider further, there is very little margin for error with a ten gallon tank. Any condition issues (nitrates, ammonia) from fish waste or excess food will only be exacerbated due to the small volume. Basically if any of your water conditions are out of wack you will need to react and rectify very fast whereas with a larger tank it takes longer for water quality to deteriorate giving you more time to fix.

Also curious if this tank was cycled properly? Did you ever test the water parameters? Crash seems to be breathing fairly heavily which could be an indicator of nitrites in the water.

I never have tested my water but Crash was breathing heavy right then because I was feeding them right before the video and he chases the others when he sees them thats why I tried setting up the slate so he cant see to the other side it has worked in keeping them safe for the most part but obviously still wasnt enough for him to back off completely.
