I've had my loach Sharkie for over a year now. He was a birthday gift from a friend. Now I'm beginning to wonder if I have the space for him. :l He is an orange-finned loach (there seems to be varying scientific names?). I'm doing research and it looks like he might get 7-9 inches long. Also, could he be stunted? I was stupid when I first got him and only had a 10 gallon tank (I shudder when I recall how overstocked that was). He's only about 4 inches. My tank's length is 48 inches and the height is 18. Can I get verification on how many gallons that is? Was told it is a 55 gallon tank. I would like to provide him with a good home with me, however I am worried that I can't. He needs friends but I dont have the space, and it's not recommended to just have two or three as the dominant one could bully the others. Sharkie has a cave to hide in and I'm planning on buying a piece of driftwood. I am 14, please keep that in mind when it comes to buying things.
