I hav 6 tiger barbs in my tank
if they can destroy plants, does that means that i can’t have live plants in the tank???
These small birds are eating all the leaves on my sunflowers. I’ve tried spraying bug poison and laying snail bait (in case it was snails). The other dfay I was out there and actually saw 3 brids eating the leaves. I can’t cage the plants, so that’s not an option. Help?
These birds keep taking moss that I lay down in my garden. I guess they use it for their nests. I know a couple ways to keep them out, but I want to know the cheapest most effective solution to this problem.
P.S I cant remove the moss, the plants require it to be there.
These plants are also sensitive to chemecals
What do you do when a endangered animal eats endangered plants?
Will they get along okay? And the tank is freshwater, with many plants.
Thanks!
If I need to, we can take the betta out.
I’m a total vegetarian, but I’m writing an essay.
Theres a lot of them in California and just fields and fields of grass and cows.
Duh, plants are living, but they can’t feel emotion, pain, or saddness. They may be able to emit chemicals and such, but they can’t feel emotion. You argumentative people really need to think more clearly.
At work, they have several bird cages with parrots. It is cruel enough that they are locked up in there (God, I feel like opening the door for them), what can i do to make them feel better? Are there any toys or plants hat birds would like in their life prison?
I have 2 birds. A female zebra finch and a male house sparrow. They both get time out of the cage during the day when I’m home. At night before I got to bed I turn out the lights for my aquarium and plants, cover their cage then turn out my room light. Usually 5-10 minutes after the lights go out my birds start to freak. I can hear them flying frantically within the cage. Thankfully it doesn’t last long but why do they do it?
I say garden but really it’s a tiny (2 meters by 3 meters) cobbled courtyard. It’s walled off and has plants round the perimeter, mostly year long greens, ivy and some seasonal flowers.
There’s a small fountain in the wall which has fresh water.
Now I put out bread every day and get the most adorable little birds, I’d love to do more (am a sucker for animals) so is there anything else? Do I have to wait till winter for balls of seeds?
