He seems sick and is floating on top of the water all the time. I have bought him for two days from a LFS. When he was bought , his tail was alrdy been nipped before by other fishes when he was at the LFS . He just ignores the food that i gave him. The other types of gourami in my tank was doing well and seems happy , only him. How can i make him happier ? There are live plants and driftwood which provide alot of hiding spaces for them. Its an 15 gallon tank , with 3 dwarf gourami which is very friendly to each other. I also have 9 neon tetras . & i also have some shrimps before , but now only 2 cherry and 1 malayan shrimp remains. Any idea ? Is it overstocked ? Should i return the honey gourami to the LFS where i bought it back ? But i really want it to be in my tank so if theres anyhow you can help me i'll be glad.
