I have a 30 gallon tank with two orandas. The red cap is either stuck at the bottom when I put charcoal filtration in, or stuck at the top when I put polishing filter in.
The PH is at 7.5, Ammonia and nitrates are good. I do a about a 10% water change weekly, and 50% monthly.
I recently bought a different brand of charcoal and mixed it with the old brand could this be a problem.
Melefix if anything makes the situation a little worse
What do you mean by the ammonia and nitrates are good, please elaborate, they should both be 0. Stop doing the 50% monthly changes, and just do 25% weekly w/ a gravel vac. For filter, don't mix just use the one that comes with the kit. You said the red cap, so one, or two of them are doing that, if one, than it may be diseased seperately. Melefix should not be added until you are sure of what it is, and even then it should be added.
The ammonia is 0, the nitrates are .01 the same as the tap water here. I have a 4 year old Oranda that is doing fine. The 2 year old Red cap Oranda is having problems. I have a 350 ghr filter that doesn't use a kit. I only change around 10% weekly because with the local ph that 10% keeps it in the 7 to 7.5 range. I also have a pleco and 2 mini cats that control the bio in the gravel pretty well. There hasn't been any new fish introduced in 2 years
What are your nitrite levels? You only mention ammonia & nitrate. What type of test are you using (liquid or strips)? What type of pleco? Plecos do not belong in the same tank as fancy goldfish. Plecos (at night) are known for snacking on fancies slimecoats creating a multitude of problems.
With 5 fish in a 30g, two of them fancies, you are overstocked. I honestly would up your water changes to 50% atleast once a week, twice a week would be preferable. Your ph will remain more stable with big, frequent water changes because you are not only removing dissolved solids & other impurities but you are replenishing the buffers that are being used up in the nitrification process. Without these buffers, your ph will crash as well as your cycle.
Stop changing around your filters- you are upsetting the bacterial balance in your tank. You should only be swishing the filter in some used tank water to clean it. You want to keep your fiter until it is literally falling apart. Carbon isnt necessary & only serves as an additional expense for you. Please ask if you have any questions!
It is the nitrite level (typo)liquid test. The pleco is a female bristlenose which might be a factor the red cap spends a lot of time on the bottom. We haven't seen the pleco bother any of the others even under the moonlights
I try not to change half of the water to much the local water raises the ph significantly and I really try not to spike it more than 5 gals at a time.
I usually only use the smaller micron filter on water change day the rise the other filters and replace that evening. But recently I noticed a difference in the way the red cap behaves if I leave it in longer.
Thanks for the info! So, you have detectable nitrites. They need to be zero. Do you have any idea what you nitrate level is? They must be dangerously high with a heavily stocked tank & barely any water changes. Water changes are the only way to remove nitrates. Nitrites affect a fishes ability to assimilate oxygen as do nitrate levels above 20ppm. In sensitive fancies, the weakest fish will be the first to show symptoms such as bottom sitting or hanging at the surface. High nitrates also lowers their immune system & makes them susceptible to infections & disease as well as shortening their lifespan.
Exactly what is your taps ph after it has gassed out? Unless its extreme such as 9, you are better off doing frequent big water changes to keep your tank stable at your taps level & keeping both your nitrite & nitrate levels under control. Please get your nitrates checked as soon as possible.
I don't have a nitrate test kit I will order one today. We have a filter on our tap water just for potable use in this area. It tests at ph of 8 out of the tap. I will do frequent water changes and quarantine the pleco for a while.
When we lived in Alaska we had the exact opposite in ph problems and the pleco's were always the ones to show signs of problems first.
Do you know what type of filter it is? If it removes minerals, this is something you will need to address. A ph of 8 is perfectly fine for fancies & most breeders actually prefer a higher ph. I am a fancy fanatic as well & my tap & tanks all sit in the 7.8-8 range. Let us know how your nitrates look when you are able to test them.
I believe it does remove most every thing including giardia and microbial cysts. Will I need to use a additive for the tank.
I received my nitrate test kit. My tank is at 5ppm nitrate, .01 ppm nitrite and o on the ammonia test. I have changed quite a lot of water while I was waiting for the kit. I have quarantined the red cap. It is still eating but is having trouble with coordination. It also looks to be in a growing stage and is lenthening.
The nitrate level is very good but detectable nitrites is bit concerning- they should really be zero. Can I ask what you are feeding him? Fancies really benefit from daily veggies & quality sinking pellet. In goldfish with swimbladder issues (this is what it sounds like), a complete change in diet to a homemade gel food can be sufficient to alleviate problems that commercial foods can create. Not guarentee but its worth a try!
I have been feeding goldfish flakes and crisps most of the time. I also realized the red cap is not able to feed off the bottom, so I have been feeding 4 or 5 times a day in very small amounts and also breaking up algae wafers so it can get them in its mouth I haven't fed them much fresh stuff until recently. What is home made gel made of. The red cap goes for fresh food and the other could care less.
If you google 'homemade gel recipes for goldfish', you will find a ton of recipes. The site the GAB (goldfish and aquarium board) also has lots of recipes. Basically, its a fish protien, veggies & plain gelatin- the variations & things you can add are numerous.
We have had the red cap 2+ years. After research online I think our other oranda is a 4+ year old male and may have injured the younger female. Not sure of the sex on either but the older (when in the same tank) does nudge and hover above the younger alot.
I have slowly brough the the tank to a ph of 7.6 and the other levels to 0.
The pleco and cats have never shown and sign of aggressiveness and there aren't any bites on the orandas
The tank has become small and once the weather warms a little the older oranda may move to a neighbors oriental garden.
