I had two clown loaches, but after 3 months of having on of them died and the other one has seemed lonely ever since what shood i do buy a new clown loach to keep him happy
i have 3 in my tank. the 2 larger ones stick together while the smaller guy thinks hes a danio. But on occasion you see all 3 swimming together. They definately all sleep together in their cave.
If all your water parameters check out then i would advise 2 or 3 more. Gulping for air i think may mean an ammonia spike. Someone may come by and correct me, but i would test your water before you buy
I would DEFINITLEY test your water before you buy any more!! Has the tank cycled properly?
Also, I really don't agree with buying 2 or 3 more loaches, just to bring them home to an overstocked 30 GALLON TANK!! They need AT LEAST a 55 gallon for that many. Maybe you could put them in your large tank?? They would be MUCH happier. Or just take that healthy loach of yours back and trade him in on a smaller loach. That would be my best suggestion for you. Most LFS will give you in-store credit for a healthy fish. He would really be much happier in a larger aquarium. And there are many other loaches that are smaller....you could get a few of them instead!!!
