After buying some new corydoras we discovered that we had accidentally been given 2 teeny tiny guppies , so feeling sorry for them knowing they wouldn't survive in our larger tanks we found an old 2Ltr tank in the garage and decided to make it their new home. Along with that @AndriesJ has been wanting to try grow a plant in an HOB filter, so that's how we got to thinking about trying it with our little tank using peace in the home. The peace in the home is doing really well! And has grown a lot since we planted it 3 weeks ago. Unfortunately I didn't take any photos of the little tank when we started it. Does anyone else have plants growing in their filters? Id love to hear more about it and what kinds of plants do well. Below are some photos of the little tank. Its up against my larger tank to keep the water temp steady. I still need to add some nice low light plants and perhaps a little piece if driftwood. Ill post new pics on Monday. What do you think? And if you are wondering where the guppy's are: Thanks for reading!
