Hi! Need Help/Advice on New Ranchu. Eating Bubbles

Hello everyone! I hope I am posting in the right area.tank.thumb.png.5d6d1f3e2f48f93056b6be9f326d1355.png

     I got a 4 inch Ranchu yesterday and she keeps swimming up to the top of my tank to eat the bubbles made from the filter. She does this randomly and will go short periods of time scouring the bottom without going to the top. I really worry about her gulping air because they are prone to swim bladder issues and it makes me think there is something wrong(not oxygenated enough, some parameter is off/disease). 

My tank is a 55 gallon with two different filters. One is a pretty standard off the back and the other is an off the back that is set up kind of like a cannister(sponge, filter floss, biomedia). I seeded the tank with filter media from an established tank, and I didn't add the ranchu until nitrates showed with ammonia and nitrite being 0. I live in Vegas and the tap  PH is 8.2-8.4 and the water is extremely hard(leaves white residue on everything) so I use an R0 mix for better water conditions. 50Ro/50Tap. It barely brings the PH under 8(7.8-8). I treated the water with SeaChem Prime some Microbe-life special blend right before adding. The Ammonia might have spiked since a goldfish is a bigger bioload than what it was cycled with. The current ammonia seems to be 0 - 0.25 ppm from the test Nitrite is 0, and the Nitrate is 5 ppm. I've taken a couple inches off the top to see if the waterfall will help. Am I overreacting or do you guys have any idea what's wrong/any suggestions? Any help I greatly appreciate. Thanks!

 

Other info:
Temp is generally around 74
Main Filter: MarineLand Penguin 350 BioWheel  

Second Filter(Sponge, Floss, BioMedia(rocks)): TopFin Power Filter 75

Last Water Change: Yesterday 15% percent water change before adding fish

Fish will eat and is acting normal otherwise. Food: Hikari Lionhead. She has been lightly fed as to avoid an ammonia spike.

Hey there! I wouldn’t worry about the bubble eating, it shouldn’t cause any long term issues even if they do swallow some air and have some floating poo from it. Swim bladder issues are congenital, from an injury, or exacerbated temporarily by diet or tank conditions. The first two you don’t need to worry about because they’re not the issue here, and the last isn’t a concern long term because it will resolve with proper husbandry practices.

 

Basically, unless you see something wrong with the fish’s behavior or appetite, coloration, buoyancy, etc, there is nothing to worry about. And from what you’ve told us I see nothing that concerns me with your ranchu. I’m sorry you’re in an area with garbage water! Having more surface agitation is never a bad idea and I think you’re spot on that the ammonia jumped a bit just from the addition of your fish. Just do a large water change (80+%) when the ammonia registers at .25 ppms, which might be every two or three days for a week or two as the filter adjusts and matures. Otherwise I think you’re fine.

 

If, because of the water, you’d rather do a smaller change daily to keep the ammonia under control, that’s also an option. Use your best judgment on what will cause your fish the least stress.

Also don’t bother with reverse osmosis water. The hard and alkaline water actually makes for happy goldfish, and RO water isn’t good for their osmotic balance at all.

Really, you think even a mix with conditioned Tap could be bad for them? Hmm maybe I should start just adding conditioned tap only 😅. Thanks. I just really want her to be happy.

The rule of thumb is that distilled and purified water is bad for fish, for the reasons I mentioned above. We have seen more than one animal behave off and get sick in RO water over the years. We don’t know where the line is for what is neutral or safe and when it begins to cause harm in terms of hardness, but softer water is not ideal for goldfish, and at best you’re adding an unnecessary complicated step :)

 

Given than many of us keep our goldfish in alkaline, hard water (mine is always at least 8.0 too, and very heavy with calcium), it hasn’t been necessary to augment water that is hard but stable. If the pH was fluctuating I think other arguments could be made.

Alright, Thanks so much for the info! Should I start doing only tap in small water changes daily? Idk if a fish can be shocked from switching from the mix to pure tap?

Honestly it’s not a big enough swing I’d worry. Unless your fish doesn’t seem to tolerate h the changes, just change 50% out today and add in just tap water, then do normal 80-100% water changes from there on out. If your ranchu seems to bottom sit or act ‘off’ after a water change we can talk about smaller, more frequent changes. But I wouldn’t borrow trouble on that - as long as it isn’t unstable, swinging water that off gassed to a drastically different set of parameters after a day or two, there isn’t much to worry about. The benefits of fresh water without the ammonia and nitrates far outweigh the disadvantages of a potential mineral and small pH swing. 
 

one day of transition off the RO should be PLENTY, especially given that it’s not really changing things that much.
