Hi one of my anglefish suddenly just went into a cave and layed down. its still alive but cant swim. i scooped him up with the net and it looked like he was trying real hard to swim, but just couldnt. i didnt want the other fish to pick on him so i put a breeder net in there and put him in there for now. what should i do? should i take him back to the store? i got him 3 days ago along with his friend. who seems to be fine. i think. i dont know much about these fish, but they are very lazy. seem to hide the whole time. maybe they dont like my tiger barbs?
thanks in advance for the advise!

Need to know your water parameters. Ammonia? nitrite? pH?

i dont know how to add a pic to this, but i really just took a pic of him not even an hour ago. its on here...the one who wont swim is the bigger one in the pic. if anyone wanted to see what he looks like.

Try a water change see if it helps him, how old is the tank?

As suggested above, do a 50% water change. Usually when a fish is laying on it's side and breathing rapidly, there is a slim chance for recovery. When one of my fish gets like that, I transfer it into a quarantine tank with all fresh water.

He probably came with a problem. I had a couple that did that before I figured out what was going on. They would try to swim but they just spun. I lost 5 of the H. Rasb.'s before I used Melafix and have 2 survivors/thrivers left.
Also, as far as I have heard, barbs are fin nippers which is not good with angelfish.
