Risk to fish (perching?) with big BTA

[Fitz19d]

Ok, another question I've thought of. Once my 210 is squared away and my >1ft diameter RBTA gets settled in. Would I have to worry about a fish getting lost in it due to it's size? Particularly my fumanchu or mandarin? Or is that mainly carpets that are a concern? (I have a dime sized mini carpet with suprising grip)

BTAs are not risk for fish. RBTA will be fine with any fish
