Thank you very much for your quick but thorough reply, I completely understand where you're coming from now.
But I feel very idiotic and guilty- mainly for taking a pet shop workers opinion seriously. -_-
He stated that he'd been caring for them for at least 11 years, and kept the Kuhlis and weather loaches in the same tank together at the store.
He insisted they could live together. Many did mention that kuhli's and dojos were incompatible. Seeing as how the shop owner (not worker, owner) insisted he kept them together for years, I came to the conclusion that it was the idea that the loaches weren't good tank mates (as in they didn't get along).
I feel very stupid for ever buying into it, but I assure you that it will be no trouble for me to relocate my dojo loach to a safe, cooler & larger tank in the morning. I do have my 20, my 10 and a small 5 gallon, but my friend Byron I mentioned before (he used to care for Bala sharks) has a 55 he's often shared the space of with me. No balas in there now. Only Pictus catfish and a few dojos.
I'm very disappointed in how I've been doing so far, it seems I'm not off to a very good start, am I.

But I assure you, I really do have my fishes best interests in thought.
As for the discussions going on throughout the board, this disturbs me slightly. If anyone on here is finding I'm going about things wrong, how come they've offered no posts saying 'hey, I think you're doing this and this wrong, and you should go about things this way.' I am new to this and can't find things out any other way then either being told how to go about it, or finding out the hard way. Talking amongst yourselves is not only something I find rude, but in no way beneficial to myself or my fish that you fear are in danger.
Sorry if I'm coming off hostile, it isn't my intent.
I just find it disheartening that if anyone is finding I'm doing anything harmful to or for my fish, they murmur it to each other and not to who needs to hear it most, and that's me.
It's sort of like a bunch of people standing around & watching a fist fight- either someone loses in it, or someone offers a solution.
Please, if anyone possesses valuable to offer me, (sort of like the post I just got above) I'd really appreciate it being told to me- the only thing I can take offense to is silence.
Thanks for letting me know angelfish83, I'll move Indie to the 55 tomorrow, and hopefully from there on in I can move forward in what I'm doing. I hope the move is appreciated, and improves her lifestyle. There are many hiding places in my 20 and Byron's 55.
Are there any answers to the questions I asked in the first post?
And my Kuhli is fine with the Serpae, am I correct? I heard they are fin nippers, but being in a small group of 6 I haven't seen them act on this title- only when they were first introduced to my rainbow. One of them tried to take a nip at him and my rainbow put him in his place.

There's been no conflict since. Opinions?
