Hey guys, help me out here.
First off, I am not sure I should add anything. I am not having a good time feeding these fish it seems. Let me start
My biggest tank, 360 liters, 120x50x60 cm. Have had it for 12 years or so, and remade the inhabitants in the past 5 years a few times. Remade the substrate last summer too. Now it is half in the back some clay substrate, the front is sand.

Pictures are pre maintenace, I have a plan today to hook the pennywort back on the sticks to not have a weird ball floating there, and I will cutt he sword leaves that are not doing well

Right now I have 4 pearl gouramis, 10 rummynose tetras, 20 or so WCMM that I moved from my other tanks, all around 2 years old lot I am shuffling around as they are super easy to catch. 3 bolivian rams, all males, waiting for some grown up females to add, but I have had them for 2 years now, had them with female that I lost last year stuck behind a heater, had them lay and guard eggs and had ZERO issues. I also have some leftover otocinclus that I have had for few years now, and around 10 or 15 kuhli loaches. Well not all kuhli loaches, at least 3 must be myersi, they are 5 times as big, different stripe pattern. They never hide, they are always wiggling around, they eat well, zero issues with other fish. Tank has a coconut cave, another cave, some wood, lot of shaded places and two flower pots with what used to be java ferns, for the kuhlies to hang around in. And they do. The plants not so much.
Last summer I bought 4 rineloricaria sp.red (red lizzard catfish I believe). I would see them ALL the time, hanging from surface plants, on the sponge filter, on the glass. But now I am down to 1 last, no idea why the othes died. Must be my feeding.
I had issues feeding bottom dwelling corydoars, that I used to have in the tank. I feed a lot of micro foods, live bbs, microworms, frozen cyclops, rotifers, mosquito larvae, daphnia. I will feed insect granulates like fluval bug bite, hikari vibra bites, micro pellets, spirulina powder. When I try any waffers, all the other fish go for them first. Even when I drop them in after lights out. I always feed a cloud and into the stream and all the othe fish seem to manage, the bolivian rams eat from near the surface, even the kuhli loaches have no issues. But not the previous corydoras, not the whiptails.

I wonder, I sometimes still want another fish. Like some sort of ancistrus. I am iffy on the english names, in here, we call them Lnumbers, there are SO MANY sold here. Not just some old "boring" brown pleco (is that the correct english name?) or a long fin, but snow, zebra, spotted. We for some reason also have a lot of panaque, like anyone has the tank size for that. Just last week at a fair I saw a 15-20 cm specimin of the green one with the blue eyes. So pretty!!


Should I get one? If yes, which one? My plants are barely holding, the swords look worse than ever. How should I feed? I will drop a vegetable once a week, zuchinni, cucumbers, leaves, there is leaf litter. I put a broccoli in yesterday that is now stuck under the branches and full of kuhli loaches, all the otos hower nearby. Rummynose love spinach.... I will occasionally drop in a small piece of fruit, just for fun.


I managed to take a picture of the loricaria that must have died recently, two weeks ago it changed color to white. Seemed ok otherwise, behaved fine, but the color... and now there is only one in the tank

Yes I know about the algae. I have to buy a new eheim filter output green spray bar, that costs so much money for no reason. To be fair I think I have had this one for the whole 12 years.
Thanks!
 
I have a few plecos... but one of the best tank cleaners I currently have are Oto's there are giant ones, ( not really an Oto, but I didn't name them ) but I'm really fond of the Zebra Oto's they keep my large anubias clear, there are a few in this picture

I am not looking for a "cleaner" per say, like that is my problem I have algae. I just want a fish that is going to be comfortable in the tank, fit well with others, I will see it sometimes and will be interesting. I do not think I have a place for another dominant fish or another school though.
 
Unless you permit the algae and biofilm to grow, you shouldn't get an algae eater. Overly clean tanks kill fish, even if clean water is essential. You have to differentiate between the water and the solid objects.

With each "L number" that appeals to you, you have to do research first. The Loracarid group is, in my opinion, the most research intensive group of fish you can encounter. They are diverse in their needs and feeding, and like all evolved specialists, don't always do well outside of whatever strange biotope they come from. You have to adjust to their needs. Many can't adapt to your tank, or to what you want.

That doesn't always make them good community fish.

I have access to wild imports, and sometimes the list of available Loracarids runs to more than 20 species I'm not very familiar with. I have thought it would be interesting to choose a species and learn more, but as I work through those species, checking 2 or 3 sources online for each one, I just seem to eliminate them as possibilities. This one needs a diet I can't offer. That one needs a high water flow. The next one grows too large. Some are predators, omnivores, herbivores, wood eaters... and some are too expensive.

I enjoy the research because they are such complex beasts, but I won't order any until I know what I'm doing, and that they fit. So far, none have fit cleanly with my set ups.

I assumed this was an issue just for otocinclus. But this tank has been running like this for 4 years. Most of the wood or plants have been in for at least a year. I only wash two glasses from spot algae when I cant see in, otherwise I do not. I leave the plant leaves in, I have a leaf litter and botanicals. And, obviously, I have black algae. though in this tank, in the past year or so, zero green algae. But hence the repashy/spirulina feeding
I would say the biofilm is there. Wouldnt you?
 
It should be. Now, the last Loracarid I wanted to buy didn't primarily eat bioflm OR algae. Plus, as I dug deeper, it came from very fast water. I could have run a tank for it, but not with other fish.

I loved the looks of it, but it went onto the "I wish" list.
