In the reaction:

\[
\text{H}_2\text{Se} + \text{H}_2\text{O} \rightarrow \text{SeH}^- + \text{H}_3\text{O}^+
\]

we can identify the acid, base, conjugate acid, and conjugate base as follows:

1. **Acid**: \(\text{H}_2\text{Se}\) (dihydrogen selenide) is acting as the acid because it donates a proton (H⁺).

2. **Base**: \(\text{H}_2\text{O}\) (water) is acting as the base because it accepts a proton (H⁺) to form the hydronium ion.

3. **Conjugate Acid**: \(\text{H}_3\text{O}^+\) (hydronium ion) is the conjugate acid of water. It is formed when water accepts a proton.

4. **Conjugate Base**: \(\text{SeH}^-\) (selenide ion) is the conjugate base of \(\text{H}_2\text{Se}\). It is formed when \(\text{H}_2\text{Se}\) donates a proton.

So, to summarize:
- Acid: \(\text{H}_2\text{Se}\)
- Base: \(\text{H}_2\text{O}\)
- Conjugate Acid: \(\text{H}_3\text{O}^+\)
- Conjugate Base: \(\text{SeH}^-\)
