Verdict
The clearest difference is in-app purchases: Quantum Aqua at none against Fish Disease Identifier's 2. Quantum Aqua also leads on iOS requirement (13.0 vs 15.1). Fish Disease Identifier's advantage is update cadence (weekly vs every 4 weeks). On price, ads and device support there is nothing between them.
