help... I’m not complaining much this 18gallon tank has my two Dwarf gouramis(third one of mine died last week due to illness, he had dropsy and when I dissected the body, which isn’t easy for me I found out he had organ failure, organs had yellow and white patches, lucky for me I spotted it early and quarantined him so my other two were not affected), 3 corydoras(2 albinos, 1 salt and pepper), 3 ghost shrimp, 6 fancy guppies(newest edition). I’ve also added some plants like lucky bamboo, some carpet plant(I don’t gravel vac so I decided on carpet plants) I found at a LFS, three floaty plants for the gouramis cause I felt my java ferns and marimo moss ball wasn’t enough(it would be great for someone to help identify the plants. The only problem is the the corydoras keep uprooting the carpet plants. P.S I don’t use soil I use gravel cause I believe my fishes poop is sufficient nutrients for the plants. I can’t use super glue nor can I tie them down what other options do I have. Here’s a picture of the tank. Btw my dwarf gouramis are surprisingly peaceful only with the seldom chase, no nipping. They don’t flare up as often, and they leave my other fish alone. Ironically It’s more like the guppies own the tank now despite the two cousins of the betta.
