Harlequin Rasbora missing Pectoral fin
I got 3 Harlequins yesterday from Petsmart and one is missing a right pectoral fin. Also it's pretty skinny at the moment but hopefully I'll be able to fatten it up. The 3 are in a holding tank at the moment and it seems that the one missing the fin is a loner. Do you think he'll be able to school with the rest once I add him and his 2 buddies to the tank with the rest of the Harlequin school? I hope he doesn't get picked on because of his disability :|

His fin should grow back over time. He may have been bullied, so watch how the others treat him. If you see a bully I'd suggest taking either him, or the bully back though, otherwise it may get worse. Sometimes it takes a bit before they let in a loner with minimal nipping, so if they don't run him down or chew on him, they'll probably let him in once he starts feeling more secure.

So, if he's not sick, doesn't get picked on or have an infection, his fin should repair pretty quickly(within a month or so usually) and he should fatten up. =)

Keep a close eye on him, if he doesn't start gaining weight within a few days, at least a little, it's possible he's got a parasite, so keep him and the other two newbies in your holding tank for at least two or three weeks, unless you see something, then treat it and keep them separate from other tanks and fish longer.

Thanks, excellent info... he is eating and seems to have some tail rot but should clean up when the food strengthens his immune system. I'm glad he is eating for now.

Clean water, low stress and time regrows fins.

Well guys, he didn't make it. I got a replacement from Petsmart along with a free water test... of course I took a sample of water from the main tank, lol. Turns out my water is perfect according to their little strip tests.

Strips, ugh! Awful things, rarely accurate. You should get a proper liquid testing kit. When I got a test kit, I found out just how wrong my strips really were. Petshops -always- say "You're water is perfect" occasionally they'll tell you if there is a bit of ammonia and that you should do a water change...and without knowing what kind of fish you have and asking about the tank, they certainly can't know if it's perfect.

I'm sorry the little guy didn't make it. =( Sometimes no matter what you do they just can't do it. I have a tetra who came in with a ripped dorsal fin and ich. He's recovering well, unfortunately the five others purchased with him did not make it. I only had two survivors from the seven bought. It sucks to lose fish!

I thought the little guy was going to pull through but I found it today swimming erratically in circles then crashing on its side breathing heavily. The other 2 are doing well though... for Petsmart, 2 out of 3 isn't too bad, hah.

Ah, when they swim around like that it can mean a lot of things. But likely something in the water(or a really nasty swimbladder infection). I really do think you should get a proper testing kit, and do a large water change just in case. It can't hurt. ^^;

Well, I'm a fan of filtration. On my 33 gallon, I've got 2 Aquaclear 50s (200gph x2) as well as an Undergravel and on my 16 gallon, I've got an external Aqueon 10 (100gph) and an internal Aqueon AT40 (158gph). I do 10%-25% water change weekly.
