Yea I have live plants and pumps in mine as well. Maybe its just because I was used to see them at the lower temperature. I will add more air pumpsand maybe another power head
There’s two parts to dissolved oxygen in water. Maybe more but for fish keeping two is enough.
First - The physics/chemistry behind dissolved oxygen in water is temperature. Temperature allows water to hold dissolved oxygen, the colder the water the more dissolved oxygen it can hold. The warmer the water the less dissolved oxygen it can hold. That’s all there is to it.
Second – Oxygen is transferred and dissolved into the water through the water’s surface area, the top of the tank, the part where the water meets the air. The lungs of a fish tank is the surface area of the tank. Bubblers help in transferring oxygen to the water by breaking the surface area and splashing the water’s surface. Bubblers create openings in the water’s surface that is covered with oils from feeding and fish poo and so on. It’s very important to have surface agitation to keep the water’s oxygen saturation to the maximum allowed by the temperature. Overflows are great for skimming the water’s surface of oils allowing for the maximum amount of oxygen to be dissolved.
Ultimately the waters temperature determines the amount of dissolved oxygen that can be in the water. Not the bubblers, not water movement, not injecting pure o2 into the water, it is impossible to get more oxygen into warmer water. It’s kinda like gravity, it is what it is.
As an animal grows it needs more oxygen. As our Goonches grow they will need more oxygen. Colder water will be key. These fish have adapted to a cold water environment, smaller gills and so on.
Good luck in your Goonch keeping, I can’t wait for one of us to grow out a 3 footer.
Egon i agree that the temperature influences the MAX oxygen water can hold, however realistically speaking most tanks and or streams or rivers are not maxed out in their oxygen carrying capacity.... that being said, by adding more bubblers and more surface agitation an 80 degree tank can hold as much as a 70 degree tank with less bubblers.... thats my point, that by adding a ton of bubblers, the wet/dry trickle system, lots of surface current i am working to maximize the amount of oxygen my tanks water has..... is there a chance the extra bubblers serve no purpose because the tanks water is already maxed out in oxygen carrying capacity .... yes, but i highly doubt it.... not to mention the added ability of the water to expel CO2 and other gases with the trickle filter the water is better able to breath.... i'm not trying to say keeping a cold water fish in tropical water is morally right, cause it is not, however one can say keeping any fish in a tank is also not morally right.... i'm just saying that by maximizing the dissolved oxygen in the water via bubblers, surface movement, and the trickle filter i am trying to negate the fact that warmer water holds less oxygen, therefor allowing the goonch to breath just fine.... i'm sure there are other problems associated with keeping the fish in very warm waters i'm just trying to compensate the best i can..... and yes i want to see one of our goonches break the 3 foot mark VERY! badly! hahaha

Sounds like we agree. I'm not saying keeping a Goonch in 80 degree temps is morally wrong. I personally struggle with keeping my Goonch tank below 80 in the summer here in Phoenix. Fortunately the air here is very dry and I keep my Goonch tank open, no cover. I have a large ceiling fan above it keeping the water as cool as possible. But it still reaches into the low 80's sometimes. Every year it seems to be another 6" larger and every year I cross my fingers hopping it makes it through the summer. I just don't want someone to accidentally kill their Goonch trying to maximize it's growth when they seem to grow rapidly in cooler temps. Anyway it's good conversation, cheers
i know what you mean, everytime mine act a little strange i get nervous, but i guess, much like us, they can thrive in varying habitats.... i'm sure sunny pools are lower in oxygen and higher temp than running rapids, i just get nervous i'm pushing their tolerance, but then again the fish would tell us with behavior that they dont like their environment .... either way cheers to you sir, and the biggest goonch out there! haha

I feel one of the major reasons as egon had stated earlier that cooler water is essential once the goonch gets to a certain size. I feel this is why there is so much goonch die out past 30 inches. I predict egons will be the first to happily push that mark. Once my goonch gets to 18" I am dropping my temp down from 78 to 70.
In honor of this thread being made sticky I will sneak down to the goonch tanks and take a few flash shots!
