looking good. what size tank are you going to move him into? What's the story on tankmates for him?
He will be goin into a 120liter tank solo. His tankmate history so far is he views them as food. Thats mostly my own fault to be honest, trying to house him with fish to small. I have a feeling he would do fine with bigger cichlids and polypterus for example since generally he is not overly aggressive. Maybe I will move him to a bigger tank with bigger tankmatea later, but going to keep him for a while solo in a planted tank.

Never had one but I think they are one of those inch per month until 6 inch fish... then it’s a crawl from there, like a lot of those predatory characins.

My Erythrinus went from a skinny 2.5-3 fish to a 6 inch cigar in six months. I didn't feed any live food except for the occasional earthworm from the yard. He ate mostly NLS pellets, Fluval Bug Bites and the a piece of shrimp or tilapia when I few the plecos. Max size is 8 inch or so, if I remember correctly.

They are potentially supposed to be able to reach 10 inches I think, but those last inches are probably really slow

Dear Monsterfishkeepers, I seek your advise. My 185liters/50gal currently holds:
1 pair Herotilapia Multispinosa
1 female Salvini
5 Mollies
3 tiny ancistrus

The thing is that the cichlids are all very skittish and mostly hide and the tank feels empty and lifeless most of the time. I added the mollies as dithers but they didn't have much of an effect. I have added more natural decor in hope of more lively activity but it doesn't do the trick. The mollies do add a little bit of life to the tank but only a little bit, plus their coloration kind of blends in with the environment (note, I am not looking for more color, just more activity).
The salvini is the most skittish and hides the most but the rainbows are almost as bad.
The water quality is always good, I measure weekly. Ammonia never been above 0, nitrites never been above 0 and nitrates never been above 10 and usually are 0.
I do weekly waterchanges (about 30% usually).
My water is very soft, 6-6.5 usually in the tank, I know the fish prefer it harder but I am fairly certain that they were bred in the same waterparameters, possibly for generations even.
Bright lights are also not the problem, my lighting is very moderate.

Are there any suggestions on how to bring more life to the tank? I am open for all suggestions, decor, added fish, removing fish, complete change of stock, anything.
Thanks in advance for all suggestions :)

Here is a pic of the tank now.

I would seriously consider increasing the hardness of the water first (if it is truly soft water with low TDS and Low GH). Sticking hard water fish in soft water (low PH low TDS), causes them to release minerals out of their body quicker than they would like. This causes stress, so I am not surprised the softer water is making it harder for them to feel comfortable.

You really need to measure the water KH and GH or the TDS to determine if your water is truly soft water. PH is not a measure of hard water, it is a measure of acidity/alkalinity.

Good point, and yes sorry about sticking the oh value in there it was supposed to be GH(measured weekly). The gh is usually between 0-75 and KH ~ 0 as well :(
