It really depends on the rate you're pupping co2 into the water.
The 'plant growing theory' is that you keep the CO2 running during the siesta to allow CO2 levels to replenish so the plants have an optimal starting point once the lights come back on again. In this plant-bias method the co2 also comes on an hour before lights come on for the same reason. However this is aimed at optimal plant growth and may not be overly great for fish.
I ran a hi-tech planted tank for over a year with high co2 levels and kept the co2 on during the siesta; the plants grew great and i didn't notice anything wrong with the fish. However since moving i've not been able to set up the co2 and i now realise my fish are feeling a lot better for it - i just didn't realise how lethargic they were with the high co2 levels.
i think i'll be turning my co2 down and reducing the lighting but keeping it on over the siesta once i have it set up again.
Haha i now have an image me of slapping a fish round the face in my head - it's all a bit too tempting given the circumstances! But in all honesty I don't think i'm around enough during the day enough to be consistent with any behaviour-training.
I was considering adding more fish - i'd probably comfortably get another 2 goldies in the tank providing i keep on top of water changes - but i'm just worried she'll attack any new comers as well since she's already 'killed' one.
Have ordered my bit-and-pieces to make the tank divide so i'll stick to that for now.
Yep, Newbie is about a third of the size of the older fish.
I don't think it's food related either as she's too preoccupied with food to fight. I wish older fish would have a go back to teach her a lesson but not sure that's going to happen as he seems scared of her now.
looks like tank divide is the only immediate solution anyway; as i don't have room for another tank and can't keep a goldie long term in the 40L quarantine tank and above all i need to give older fish's fins time to heal again
I have a problem - has anyone ever experienced an aggressive fin-nipping goldie? My boyfriend decided to surprise me with a new goldfish a couple of months ago and this [insert expletives] fish is driving me insane with what seems like really aggressive and premeditated fin-nipping.
When I say she?s fin-nipping it?s more like ripping-to-shreds ? you?ve all probably seen goldies shred plant leaves off now replace that plant with a tail and that?s what she does. She?s already effectively killed one of the fish (who got a bacterial infection as a result of the fin-nipping and never recovered) and the other goldie got velvet as a result of the stress.
Water quality ? ammonia 0, nitrite 0, nitrate <10 dosing - 10ml easycarbo every day, 10ml TPN+ once a week Feeding ? twice a day, varied between: tetrafin gold japan, Tera Natura Algae Mix, Tetra Natura Bloodworm mix, frozen spinach, frozen brine shrimp, frozen bloodworm and the occasional peas and courgette and broccoli and excess Salvinia natans from the tropical tank (when it threatens to take over)
This has been my train of thought about why she does it: Boredom ? possible, but has plenty of plants and hiding places not sure what else to give them Territory ? 240L fluval roma with 2 goldies <4 inches long? doubtful mating behavior - well she?s female and he?s male so it?s the wrong way round and as I explain above this is ripping of tail not a slight nibble Hunger ? I used to just feed once a day but noticed they were getting a bit lethargic with the strongish flow in the tank so have upped it to twice a day Mistaking tail for floaty-plants ? possible but even when the fish swims off she actively chases them to start the nipping again
I?m at my wits end and was about to take her back to the LFS after seeing my other goldie?s tail torn to shreds again but boyfriend made me feel guilty so now I?m off to buy a tank divider so she can live in isolation before she kills the other one
Hi guys - does anyone have experience of raising oto fry?
I've just witnessed my otos embraced in the t-position and can see a few clusters of eggs where they've been embraced and i'd love to try raising them :)
My main concerns are around 1) what do i feed them if/when they hatch; and 2) should i move them to another tank as they're in with 1 male Tateurndina ocellicauda and several Pseudomugil furcatus both of which seem to try and eat anything they can get their tiny mouths around!
Greatly appreciate any advice and I feel really privileged i got to witness them breeding
