How Does This Even Work?

  • We are currently upgrading MFK. thanks! -neo
I would not keep 3 RD's in a 75.. but it's obviously working. I've seen far worse, this is not even a drop in the bucket when it comes to overcrowding. JDM ftw.
 
It could be working because, maybe they all grew up together, they're all the same sex and there isn't enough room to establish a terratory. I wouldn't do it, but that is how it could be working.

x2. I wouldn't do this even in my big tank, but to each his own I guess. They do look quite large and healthy. Sad they are such a small tank though
 
You know, I believe a fish should have plenty of room to swim, but videos like this make you curious if that is entirely true. You here about massacres happening in 600 gallon tanks, and you look at a tank like this with 3 Beautiful and healthy devils in there. No nipped fins, great body shape and big nuchal humps. Do we over estimate the amount of space a fish requires? As cichlid owners we all know that it doesn't matter the size of the tank, if you get a "killer", they will be a "killer" no matter the size of the tank.

true, to a point. A few weeks ago, my daughter and I stopped by Petsmart to pick up some dog food, and while stopping by the fish dept she spotted a rather larger Albino Zebra(mbuna) wrecking havoc in a display tank. Just terrorizing all the fish in there. She wanted the fish and the woman in the fish dept knew we had a 135 malawi setup, so she asked us to take it. Reluctantly, we did under the premise that if it was too aggressive, he would be returned.........he couldn't be a nicer fish in the 6 footer with space. Calm as could be and although larger than most of his tank mates, he is far from the killer we witnessed in the store

On the flip side, I tried introducing what seemed to be a very peaceful jag to my large display that has tons of space and it was armageddon within several days.....

You just never know how cichlids will behave......

That's my point on the 3 Devils. Though they are seemingly peaceful, there was a bit of aggression between 2 of the 3 at one point. There could come a moment one snaps and all hell breaks loose. I don't agree with putting large fish in small tanks. It's like keeping a big dog in a cage just big enough for it.

I don't know enough about these fish to say if they are "healthy". For one there is no mention of how the water parameters are and second the water level is kinda low which probably means its been a while since the last water change.

But even if everything was perfect as far as water quality and compatability goes I still would not keep them in that small of a tank. I believe that size of tank is just as important as water clarity. I believe a fish should have space to swim and I am not a fan of overcrowding when it comes to centrals.

agreed. Crowding fish to suit the need s of hobbyists is just not my thing......even with Mbuna I stock a lot lighter than most
 
I wouldn't called being depressed peaceful :-p I just find it a little insulting, that some over crowded tanks are ok, but there others with 50% less bioload then that 75g get the earbashing of a lifetime and probabley don't use this site again, I have myself been put off by the lectures you receive on here. Just goes to show, one rule for one, one rule for another. I do believe if a overcrowded tank works and the fsh are fine brilliant, but not fish of that aggression or size. I personally never disclose my stock on this site as there will always be someone to pick fault. I just find it interesting that someone will get verbal earbashings for keeping 2 oscars in a 55 and yet this 75 with 3 red devils is ok?
