There are some aquatic plants that you can literally throw them in the tank, any lighting, no ferts and they will grow. You could even attached the two to the rocks. Anubias and java fern. Those two are super easy and hardy plants.
Anacharis is also easy and it is a stem so you can keep getting more pieces as it grows.
Maybe I need to get some of these. Thanks for the heads up. I did some research into the plants before getting the bigger tank, but didn't find an economical solution. Maybe I'll just bite the bullet once a week and start adding a little at a time.
The problem with the gravel is once you've added it to the tank you're sort of stuck with it.
I don't recommend mixing smaller gravel with the ones you have now, but totally up to you. You can try it.
The type of shrimp pellets & sinking foods I feed my cories are the type of food that slowly softens and is meant to be slowly eaten. The fish need to WORK on the piece of food in order to get all the nutrients. These are not really designed to be a 1 bite thing.
Unless you're feeding flakes, but cories aren't designed to eat flaked foods.
With the size of your stones, there's a good chance your cories aren't getting enough food because it gets trapped in the gravel before they can actually eat it.
A turtle can move rocks that size, but most fish can't.
Make sure you take pictures before you change anything.
I really like the size of your tank and all the different options available. Also I have to keep an eye out for decorations like yours.
NEVER! I won't ever be stuck with anything
. I still have the 10g that I can put all of them into for a bit if I want to change something.
Is there a reason you don't suggest the smaller gravel? I feel like it would end up being a layer on top of what's there now. maybe even glowing gravel?
Feeding tiny sinking pellets right now for the tetras and cories. The danios eat anything that gets near them, so lots of tiny pellets give the tetras a chance to get at them. Now that you mention it, the cories are ALWAYS swimming around frantically looking for food. I figured that was kinda normal, though.
I've seen all of those decorations at petsmart.
