Dicrossus 420 L

[Gaisller]

Yeah was speaking about lighting, sorry.
Thank you. You don't have problem with humidity ?

So far so good. I didn't notice any problem.

The spots are fixed in the wall behind the tank.

 

[Gaisller]

All the cianos are gone!

I noticed that the male dicrossus is being super aggressive to two females. The other two females are ok but they are also aggressive towards the same females. Is it breeding behavior? There is something that I could do to help?

This is territorial aggression. The less dominant females may eventually succumb to stress related illness if not removed. I wouldn't worry about breeding in a tank full of fry predators like yours. You would be better off if you only had a 3 of males in the tank.

This fishes are pure evil... Saddly, one female died yesterday.

The male and the other two females are doing great, but there is one last female that is being attacked by 'em. It does not look to do much damage, but the stress is what concerns me. Actually, the male does not damage the female, looks that he is trying to get her attention. But he is doing it all the time, so she hides ate the corner of the tank.

Some more pictures:

Also, I added two Otocinclus (?). I would appreciate if you help me with the ID of it btw.

Yeah, they are not brutally violent like e.g. Pelvicachromis but they are relentless. The only chance for this female is being removed from the tank.

Could this be “Hypoptopoma Sp. Peru”?
I guess it’s a close relative to otocinclus.
Just guess-work, from my side.

Completely overlooked that (being on phone all day).
Yeah they are not Otocinclus, not Hypoptopoma, but Parotocinclus maculicauda. They prefer higher conductivity and pH than the other fish in the tank, but can do with low levels.

Otocinclus looks like it could be https://www.planetcatfish.com/common/species.php?species_id=1350

Close, but the red in the fins is telltale for P. maculicauda. Those are quite common in the hobby the past two years. O. flexilis haven't been spotted in a while.

100% agreed.

Thanks a lot, Mac.

You're welcome!

Hi all,

They have an adipose fin as well. Otocinclus spp. don't have it.

I have several of those (and knew what they were - they are often sold as 'red fin' otto). My question - is there much of a difference between them and otto? They do seem to be somewhere between pleco and otto but wanted to check if there was a real biological behavior with regards to food et all.

 

[MacZ]

My question - is there much of a difference between them and otto?

On the whole they eat aufwuchs as well, but ship far better, usually preventing the "Otocinclus Starvation Syndrome".

They definitely tick a lot of boxes to make clear they are not Otocinclus proper.

 

[Gaisller]

A little update.

 

[rasmusW]

Looks great.
What type of moss are you using here?

Thank you!

Java moss.

Guys, this isn't the theme of this forum, but I would like to know if it's ok to buy some angel fish and keep them in my tank.

Do you think it will be okay? I was thinking in 5 angels. What do you think? Does anybody have experience with angels?

Thanks!

 

[MacZ]

I'd rather not. The tank is quite low and lacking the high structures required to keep them from killing each other once they mature to adults. And once they breed it's not gonna be a good place to be for any of the other fish.

Unless your aquarium is over 6 feet long (longer the better); chances of having tranquility among the angels once a pair form is near zip. I have a 10ftx4ft aquarium and will be 'testing' at some point if the larger space will allow domestic angelfishes to get along with pairs forming. The 120 they were in definitely was not large enough to support more than a single pair (4ftx2ft); mind you for the first 2 years or so you can keep 5 or 7 in that space but as they get older sooner or later the dynamics fall apart - you'd think it would fall apart as soon as the pair forms but it seemed to take a bit longer to completely collapse if raised together. Naturally individual fishes have different personalities and your experience might differ but i tried 4 or 5 times with different sets in the 120 and things always fell completely apart by year 2.
