i googled some koi fish tattoos and i love this one! i want somethin with this coloring and design. Think it would cover up the taz?

sooo i got a tattoo i would like to cover up, its a taz tattoo. im not sure what i want yet but i want it to be bad ass or somewhat meaningful haha, idk anything about covering up tattoos really? will this one be hard to cover up? its on my upper leg. any suggestions on what to cover up it up with would be appreciated
