BTA at top of quarantine

[Ruzoko]

Soo my bta decided to move to the top of the 20g quarantine tank near the return for the sponge filter, but hes up so high removing 5 gallons for a water change will leave it out of the water, will it be alright or should i try to get him off the glass?

Yes, you could try to gently move it.
