Short version:
Looking for any experiences with rainbow sharks/red tailed sharks and panda garra specifically. I know there likely won't be many as I've only found two threads on Google so far as listed below.

Other question is if you'd risk adopting a rainbow shark along with a lone clown loach (they hang out together bc these species are said to sometimes do that and clown loach had no other clown loaches around it). I'm worried about having a problem and then being stuck with the rainbow shark myself.

On the other hand, clown loach would have another fish it already hangs out with in QT rather than being alone in QT(if I adopt the clown loach, I'm going to set up a second 10g QT bc my normal QT has a bunch of new fish, including less than an inch rummynose tetra that I fear could get eaten).


I've found two threads mentioning rainbow/RTS and panda garra:

Post #15 shows they got along. Here's a screenshot of a pic person posted:

I found another thread where a RTS was terrorizing panda garra and it also comes up on YouTube in a search. That particular person had too small a tank and poor stocking though.

Seriouslyfish says (bold mine):

Some individuals may be more belligerent than others and there exist reports of apparent alliances with other species such as Chromobotia macracanthus. We’re unsure if these behavioural differences are indicative of gender but at any rate loaches from the genera Chromobotia, Botia, Syncrossus and Yasuhikotakia do seem to be left in peace by Epalzeorhynchos species whereas congenerics and members of Crossocheilus, Garra and Gyrinocheilus, for example, tend to be attacked constantly. Please note that in terms of the loaches not all may be housed together and proper research is essential.

Other bottom-dwelling fishes including cichlids and most catfish are best avoided as they may too be picked on. For the upper levels choose robust, active, schooling cyprinids. Ideally the Epalzeorhynchos should be the final addition to the tank in order to avoid it claiming ownership of the entire space.

So that sounds bad. I worry about my hypostomus but so far, it seems that plecos usually get left alone.


Extra details that might help, but I realize this is long so above is enough to get comments:

Background:
I found clown loach that was kept alone and spends it's time next to a rainbow shark (current owner says the two sleep side by side). It would have a pretty good life (great if I do managed to upgrade to a bigger tank, but otherwise, my 125g will definitely be an upgrade for either now as they are in a 20L awaiting homes).


Current owner would like me to take rainbow shark as the clown loach and RS as close and bc it's one less fish to find a home for.

I've read mixed reports, many bad about rainbow sharks. It seems they likely do great with my clown loaches. It seems the RS would likely leave my hypostomus be alone. It would also likely leave the rainbowfish alone but there's a chance the RS could bother them.




Background story:
I guess the story is a neighbor left a 75g with an assortment of fish that need homes. Person who took tank is going to use the 75 for goldfish they already owned that were in a smaller tank. This neighbor's 75g had an assortment of fish, several which weren't stocked properly and several which shouldn't have been together:

1 Knifefish (3 yrs old)
1 shimmery pure white angelfish male (3 yrs)
1 bristlenose pleco (5 yrs old)
1 clown loach (3-4 yrs)
1 redfin shark (age unknown)
1 zebra danio (2 yrs)

These fish are currently in 20L awaiting homes.

I've suggested the person post here as I think there is more likely to be interest here for the knifefish than the other forum where I found this post.

My stocking:
I have a 125g with two larger clown loaches (one large 8" but tall and fat, one medium (probably stunted as he's like 5-6" even though he's 20+ years), and 4 small (3-4", had them a year), 12 Doritys & millennium rainbowfish, 5 panda garra, one 20+ year old hypostomus 11.5".


There's 6 praecox, 6 m. Splendida "deep water Creek", and 12 true rummynose in QT tank.

I think my tank will be close to overstocked once I move QT fish over. I'll do more water changes if necessary.

The right half of the tank has a PVC cave and another tunnel that no one really uses. It would be great if RS used that but it seems RS could decide the cave the hypostomus uses and maybe closn loaches current caves are his instead.

Anyway, any comments or opinions are appreciated. I have to make a decision in the next day or so. Thanks
 
I have a rainbow shark now for 5 years he is a bit of a bully he used to have running battles with a fire mouth cichlid I have 2 pyjama catfish he used to fight the bigger of the 2 but that stands and fight so he now picks on the smaller one he is in a 300 liter 4 foot tank but claims the whole tank .It is quite funny watching actually patrolling the whole tank. At one time I had a jd and that was one fish he didn't mess with
 
I didn't want to risk it so I took the Loach home by itself. I was going just to look but the clown Loach was a nice size and didn't have any ich or anything. Also, the tank need was only 71-2 degrees dick was okay for most if not all the fish but I knew it was further stressing the Loach. Plus, I didnt want to bother her again.

Loach has been active and eating. I feel bad bc he's solo in the tank. I wish I could have brought rainbow shark home too. Bristlenose looked good too.

The loach would eventually out grow the shark they tend to pick on fish smaller than themselves my one used to go after my senegal bichir but now the senegal is about 2-3 inches longer and the shark leaves him alone now.
 
My albino rainbow shark picks on anything swimming but leaves the bottom dwellers alone.
 
I keep my 1 inch rainbow shark with a 3 inch jack Dempsey and giant danios. They all seem to coexist with each other so far. But the rainbow shark could get more aggressive at a older age.

Lol I looked at the typos. Dang. I never understand why the spell check messes up with Chrome. I click on corrected word and gibberish pops up. Spell correct works great in text messages.

Update:
I see the Loach doing the Loach thing of swimming up and down the glass so I assume he's doing okay. He seems to eat the pellets as I see them disappear eventually. He didn't eat the repashy: he must not recognize it as food.

My plan is to deworm him with two levamisole treatments two weeks apart and a course of general cure either in between or after. I may crank heat up to 85-86 since clowns like heat and it may kill ich. I don't think there's any ich or he world have developed it when he got stressed at 61 degrees last Thursday and after spending 4 days at 71 degrees until coming to my place.
