Need a second opinion swim bladder disease?
This is my first post here.
Ok here is the scenario:
Rescued 3 standard goldfish about 8 months ago who were not fed in weeks, were in a 10 gallon tank with no aeration and the HOB filter had quit...not to mention the water was green and the small tank was 25% empty (due to water evaporation).
They now live in a 30 gallon cycled tank with the following levels:
Nitrate: 40 - 50
Filtration: 1 - aquaclear 150 AND 1 - aquaclear 20 (I have both in order to keep up with the large amount of waste that goldfish produce)
Aeration: 1 powerhead with venturi (topfin 30 gallon)
I don't use any other additives to the water except for water conditioner (aquasafe). I do a 50% water change weekly and gravel is vacuumed twice a month.
Feeding is done twice a day and only enough to last a minute or 2 (I do not over feed).
So; one of the goldfish has been on the bottom of the tank all day. He will sit there for a minute or two and then frantically dart to the top of the water (for air I suspect) and then he will settle back down to the bottom for a bit and then the cycle begins again. When I come come close to the tank he gets excited like he is going to be fed. This shows me that he still has plenty of energy. When he sits on the bottom sometimes he will roll to his side (but then he corrects himself). Ever since I rescued them this fish (at night) sleeps at like a 45 degree angle with his head pointing down.
The two other fish are totally fine.
Based on all this I have to assume that he is suffering from swim bladder disease...is this assumption likely to be correct? It is my intention too let them (all three goldfish) fast for two days and then feed them peas for two days (apparently a cure of constipation and swim bladder disease).
Any guidance would be great.
Sorry all....TYPO!!! The temperature is 68 NOT 78. And I do not use a heater in this tank.
It could be swim bladder. What are you feeding? Sinking food, or flakes that allow them to gulp air at the surface? Anything like shrimp pellets? One of my fancies recently swallowed a shrimp pellet (intended for loaches in the tank) whole and had swim bladder issues for a day after it expanded in his stomach. :roll: He was just fine after he digested though. I'd definitely try fasting for a few days- which may help clear it up on its own- and then feed the peas if that doesn't work.
The main thing that stands out parameter wise is that your nitrates are high. The 50% weekly changes are great but goldfish produce so much waste that you should probably vacuum the gravel with every water change. I've tried getting away with only the water change (no vacuuming) with my goldies but it just gets too dirty in between. I've heard that high nitrates can cause swim bladder issues in goldfish, so that would be one of the first things I'd address.
Keep us posted on how he's doing!
The first one just shows how he darts for the top of the water just (I assume to gulp air). then you will see him rest for a second on the bottom and start to tip over.
The second video shows his more typical behavior I've seem in the past day or so.
Fed them peas last night and today he seems to have more energy. Yesterday he was on the bottom 80% of the time...today so far only about 25% of the time.
