Injured Neon Tetras

n1zjd

I had recently bought some fish for a ten gallon tank that I have. I got 3 mollies and 11 neon tetras amongst other things. I was told they would do fine together but unfortunately found out otherwise. I had seen the mollies chase the neons a little, nothing extreme, but apparently after the lights go off or when I wasnt watching the tank they did more than just chase a little. I found out earlier today that the tails of 5 of the neons have been bitten! They all seem to be swimming pretty good still with the exception of one. Do you think these fish will survive? The mollies have been removed and put into another ten gallon tank until I can find a home for them. Thanks for any help/advice.

Welcome to the Forum!

What stricks me for starter you say "3 mollies and 11 neon tetras amongst other things" what ALL exactly does live in your 10g???

Mollies require hard water, higher pH. Neon's on the other hand softer water with lower pH. You will agree only one kind of water does indeed flow out of your tap...so what water do you have there?

Do you have any plants in there for the Neon's to hide?
Honestly from what you're describing I doubt they'll live long in your tank, sorry to say that. You will need to make a decision between 1 or the other there and I'd base this decision off your water here as mentioned above.

Well now Im feeling like a moron already! My tap water ph is around 7.0, I dont know if I have hard or soft water though?!? The other fish include a male beta and 2 corydoras. Im 100% positive the beta wasnt the culprit. It was the mollies for sure. I bought some live plants from the fish store but I dont have alot of them at the current time. I have a cave type decoration as well but Im sure that doesnt benefit the neons. There appears to be plenty of room for the fish I have in the tank but Im new and obviously didnt do my job well before jumping into this so please feel free to clue me in.

No need to feel bad...you're here for the reason to learn aren't you...so allow us to help you
pH 7 is neutral...you'd need to measure your KH or GH to see the level of hardness in your water, either you can get a liquid test kit for this or see if the fish store has a liquid kit they'd test for you and have them give you a NUMBER in return (not a "its ok, that means nothing) and make sure they don't test with these strips, these are HIGHLY inaccurate.

There's really little you can do at this point 1) You could return the 3 Mollies in exchange to get more cory's as they really are very sensitive fish and only feel well in group sizes (6-8) then they feel secure and are much more active. 2) You could get yourself a second larger tank (something like 15-20g) get that cycled without fish and then move your Molly's in it and stock them up to a larger group.

There's really little else you can do, its not like you could sit the Molly's down and have a talk about aggression with them and for your Neon's to be chased and harassed 24/7 is terribly stressful to them and will not be healthy in the long run to say the least.

Thanks for the reply. I have friends with tanks and I will see if they want the fish, otherwise I will have to return them. Ill buy a test kit when I go to the pet store again later this week. This tank has been running with the beta in it for more than 6 months so I decided it was time to add something else. I do plan to get a larger tank in the future. Do tails grow back or will they, at best, heal and continue with life? Im not going to just give up on them so I will just see what happens. BTW, the two corys that I have are VERY active fish. I would have got a few more but I was afraid of overstocking the tank. Ive read 1 gallon per inch of fish, I think I am over that as it is, but the tank doesnt seem like it would be crowded but Im obviously not a fish. Again, thanks for your help and for not being hard on me for being foolish. Cheers

Edit: BTW you have some beautiful tanks!

The inch of fish per gallon rule is pretty much nonsense. There number of factors it doesn't consider is absolutely huge (water chemistry requirements, aggression, predation, overall waste output, etc.).

Is this a male or female betta? I've heard stories (not just second hand rumors, either; members on this very forum have posted about it) of larger bettas making snacks of neon tetras. Even if he's fine with them now, soon enough your betta might discover that neons are edible and quite tasty.

iamntbatman - Thanks for the reply. Its a male beta and he has shown zero aggression towards any of the fish. But I agree with you 100%, and after browsing this site for a good couple hours last night viewing many different members tanks Ive realized that what I might consider not crowded, may not actually be true. After seeing how beautiful a tank can and should look Im going to take on a whole new approach to how I do things. For the time being things need to stay the way they are because I had to move the mollies to my other tank. According to Angel, chances are they wont make it anyway. My new plan is to focus on getting the tank better 'planted' with a variety of live plants and dedicate that ten gallon tank to the beta alone. Im just in awe with how beautiful a tank really can be with a variety of live plants and a small population of fish. I promise I will learn the proper way to maintain my tanks and care for my fish. I think this just may become my new addiction Cheers

You say "to the other tank"...What all do you have there on tanks and stocks....Maybe amongst them we can help you "sort" out the stocks more ideally if you like?

And don't worry about the addiction part LOL....look at our aquarium logs here for each user...see how many people have multiple set ups lol

I have another 10 gallon setup with two swordtails in it, basically my quarantine tank for new fish. I also have a 20 gallon tank that isnt in use. I have a thread on here that you can find in the Unanswered posts about a 20 gallon with built in background. Ive decided Im giving it to my sister and Im going to get either a 55 gallon or a 30 gallon tank. I really want the 55 gallon tank but not sure I have a good place for it. Although when I get my mind set on something it usually happens I have a wall in my kitchen it could go against but Im a bit worried about algae forming due to a nearby window. I do know that the only direct sunlight that comes through that window is only for a short period of time while the sun is going down, and really my current tank gets that same sunlight with zero algae problem so I guess it would be just fine. Nice, I think I just talked myself into the 55 gallon, haha!

EDIT: Still looking for an answer as to whether or not the neons tails will grow back or just heal, if they do in fact survive, which I think they all will.

I just answered your other thread. I'd find a 55g wonderful (for your headache as far as maintenance and the fish).
No worries about the window: Algae will then start developing IF 1) Tank is not maintained well (weekly water changes) 2) Your feed way too much 3) Between your lights and the plant nutrition there's no balance 4) you run high wattage lights for some 20hrs/day
So no I wouldn't worry about the window at all; I even had 55g's set ups right next to the window where they'd get direct sunlight for the greater portion of the day and had no algae whatsoever
And worst case if you're worried: Put the blinds down when the sun comes around

The Neons will heal up. If you get a 55g I'd move (and stock up) the cory over to it, move the Mollies too, then add XYZ other fish that will get along with the mollies and leave the Neon's alone in the smaller tank. It MAY work better for them all in the 55g....it may not...so pers I'd not wanna risk it, so make them a NICE Neon set up with plants in the 10g.
